134 A proposal is a set of algorithms. For non-AEAD algorithms, this includes
135 for IKE an encryption algorithm, an integrity algorithm, a pseudo random
136 function and a Diffie-Hellman group. For AEAD algorithms, instead of
137 encryption and integrity algorithms, a combined algorithm is used.
138
139 In IKEv2, multiple algorithms of the same kind can be specified in a
140 single proposal, from which one gets selected. In IKEv1, only one
141 algorithm per kind is allowed per proposal, more algorithms get implicitly
142 stripped. Use multiple proposals to offer different algorithms
143 combinations in IKEv1.
144
145 Algorithm keywords get separated using dashes. Multiple proposals may be
146 specified in a list. The special value `default` forms a
147 default proposal of supported algorithms considered safe, and is usually a
148 good choice for interoperability.

159 aggressive = mkYesNoParam no ''
160 Enables Aggressive Mode instead of Main Mode with Identity
161 Protection. Aggressive Mode is considered less secure, because the ID and

168 If the default of yes is used, Mode Config works in pull mode, where the

170 where the responder pushes down a virtual IP to the initiating peer.
171
172 Push mode is currently supported for IKEv1, but not in IKEv2. It is used

182 encap = mkYesNoParam no ''
183 To enforce UDP encapsulation of ESP packets, the IKE daemon can fake the
184 NAT detection payloads. This makes the peer believe that NAT takes place
185 on the path, forcing it to encapsulate ESP packets in UDP.

187 Usually this is not required, but it can help to work around connectivity
188 issues with too restrictive intermediary firewalls.

193 connections, and allows mobility of clients and multi-homing on servers by
194 migrating active IPsec tunnels.
195
196 Usually keeping MOBIKE enabled is unproblematic, as it is not used if the
197 peer does not indicate support for it. However, due to the design of
198 MOBIKE, IKEv2 always floats to port 4500 starting from the second
199 exchange. Some implementations don't like this behavior, hence it can be
200 disabled.

219 fragmentation). Acceptable values are `yes` (the default
220 since 5.5.1), `accept` (since versions:5.5.3),
221 `force` and `no`.
222
223 - If set to `yes`, and the peer
224 supports it, oversized IKE messages will be sent in fragments.
225 - If set to
226 `accept`, support for fragmentation is announced to the peer but the daemon
227 does not send its own messages in fragments.
228 - If set to `force` (only
229 supported for IKEv1) the initial IKE message will already be fragmented if
230 required.
231 - Finally, setting the option to `no` will disable announcing
232 support for this feature.

241 Use childless IKE_SA initiation (RFC 6023) for IKEv2, with the first
242 CHILD_SA created with a separate CREATE_CHILD_SA exchange (e.g. to use an
243 independent DH exchange for all CHILD_SAs). Acceptable values are `allow`
244 (the default), `prefer`, `force` and `never`. If set to `allow`, responders
245 will accept childless IKE_SAs (as indicated via notify in the IKE_SA_INIT
246 response) while initiators continue to create regular IKE_SAs with the first
247 CHILD_SA created during IKE_AUTH, unless the IKE_SA is initiated explicitly
248 without any children (which will fail if the responder does not support or
249 has disabled this extension). The effect of `prefer` is the same as `allow`
250 on responders, but as initiator a childless IKE_SA is initiated if the
251 responder supports it. If set to `force`, only childless initiation is
252 accepted in either role. Finally, setting the option to `never` disables
253 support for childless IKE_SAs as responder.

297 - The value `never` does never enforce such a policy, even
298 if a peer included INITIAL_CONTACT notification messages,
299 - whereas `no` replaces existing connections for the same
300 identity if a new one has the INITIAL_CONTACT notify.
301 - `keep` rejects new connection attempts if the same user
302 already has an active connection,
303 - `replace` deletes any existing connection if a new one
304 for the same user gets established.
305
306 To compare connections for uniqueness, the remote IKE identity is used. If
307 EAP or XAuth authentication is involved, the EAP-Identity or XAuth
308 username is used to enforce the uniqueness policy instead.
309
310 On initiators this setting specifies whether an INITIAL_CONTACT notify is
311 sent during IKE_AUTH if no existing connection is found with the remote
312 peer (determined by the identities of the first authentication
313 round). Unless set to `never` the client will send a notify.

319 configurations (with EAP or configuration payloads) it might not be
320 possible to actively reauthenticate as responder. The IKEv2
321 reauthentication lifetime negotiation can instruct the client to perform
322 reauthentication.
323
324 Reauthentication is disabled by default. Enabling it usually may lead to

333
334 With the default value IKE rekeying is scheduled every 4 hours, minus the

344 to rekey or reauthenticate within the specified time, the IKE_SA gets
345 closed.

453 - The IKEv1 specific `xauth` is used for XAuth or Hybrid
454 authentication,
455 - while the IKEv2 specific `eap` keyword defines EAP
456 authentication.
457 - For `xauth`, a specific backend name may be appended,
458 separated by a dash. The appropriate `xauth` backend is
459 selected to perform the XAuth exchange. For traditional XAuth, the
460 `xauth` method is usually defined in the second
461 authentication round following an initial `pubkey` (or
462 `psk`) round. Using `xauth` in the
463 first round performs Hybrid Mode client authentication.
464 - For `eap`, a specific EAP method name may be appended, separated by a
465 dash. An EAP module implementing the appropriate method is selected to
466 perform the EAP conversation.
467 - Since 5.4.0, if both peers support RFC 7427 ("Signature Authentication
468 in IKEv2") specific hash algorithms to be used during IKEv2
469 authentication may be configured. To do so use `ike:`
470 followed by a trust chain signature scheme constraint (see description
471 of the {option}`remote` section's {option}`auth`
472 keyword). For example, with `ike:pubkey-sha384-sha256`
473 a public key signature scheme with either SHA-384 or SHA-256 would get
474 used for authentication, in that order and depending on the hash
475 algorithms supported by the peer. If no specific hash algorithms are
476 configured, the default is to prefer an algorithm that matches or
477 exceeds the strength of the signature key. If no constraints with
478 `ike:` prefix are configured any signature scheme
479 constraint (without `ike:` prefix) will also apply to
480 IKEv2 authentication, unless this is disabled in
481 `strongswan.conf`. To use RSASSA-PSS signatures use
482 `rsa/pss` instead of `pubkey` or
483 `rsa` as in e.g.
484 `ike:rsa/pss-sha256`. If `pubkey` or

618 Since 5.4.0, to require a trustchain public key strength for the remote
619 side, specify the key type followed by the minimum strength in bits (for
620 example `ecdsa-384` or
621 `rsa-2048-ecdsa-256`). To limit the acceptable set of
622 hashing algorithms for trustchain validation, append hash algorithms to
623 pubkey or a key strength definition (for example
624 `pubkey-sha256-sha512`,
625 `rsa-2048-sha256-sha384-sha512` or
626 `rsa-2048-sha256-ecdsa-256-sha256-sha384`).

628 signature constraints are configured (refer to the description of the
629 {option}`local` section's {option}`auth` keyword for
630 details), such key types and hash algorithms are also applied as
631 constraints against IKEv2 signature authentication schemes used by the
632 remote side. To require RSASSA-PSS signatures use
633 `rsa/pss` instead of `pubkey` or
634 `rsa` as in e.g. `rsa/pss-sha256`. If

664 using the specified group (refer to esp_proposals for details).

667 single proposal, from which one gets selected. In IKEv1, only one

684 a combined mode algorithm is used instead of the separate

686
687 If a DH group is specified, CHILD_SA/Quick Mode rekeying and initial
688 negotiation use a separate Diffie-Hellman exchange using the specified
689 group. However, for IKEv2, the keys of the CHILD_SA created implicitly
690 with the IKE_SA will always be derived from the IKE_SA's key material. So
691 any DH group specified here will only apply when the CHILD_SA is later
692 rekeyed or is created with a separate CREATE_CHILD_SA exchange. A
693 proposal mismatch might, therefore, not immediately be noticed when the
694 SA is established, but may later cause rekeying to fail.

724 List of local traffic selectors to include in CHILD_SA. Each selector is

727 instead of a subnet definition, which gets replaced by the tunnel outer
728 address or the virtual IP, if negotiated. This is the default.
729
730 A protocol/port selector is surrounded by opening and closing square
731 brackets. Between these brackets, a numeric or getservent(3) protocol

737 backends currently support port ranges, though.
738
739 When IKEv1 is used only the first selector is interpreted, except if the
740 Cisco Unity extension plugin is used. This is due to a limitation of the
741 IKEv1 protocol, which only allows a single pair of selectors per
742 CHILD_SA. So to tunnel traffic matched by several pairs of selectors when
743 using IKEv1 several children (CHILD_SAs) have to be defined that cover
744 the selectors. The IKE daemon uses traffic selector narrowing for IKEv1,
745 the same way it is standardized and implemented for IKEv2. However, this
