A proposal is a set of algorithms. For non-AEAD algorithms, this includes

In IKEv2, multiple algorithms of the same kind can be specified in a

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

aggressive = mkYesNoParam no ''

Enables Aggressive Mode instead of Main Mode with Identity

Protection. Aggressive Mode is considered less secure, because the ID and

To enforce UDP encapsulation of ESP packets, the IKE daemon can fake the

on the path, forcing it to encapsulate ESP packets in UDP.

migrating active IPsec tunnels.
|
|
</para><para>
|
|
Usually keeping MOBIKE enabled is unproblematic, as it is not used if the

|
peer does not indicate support for it. However, due to the design of
|
|
MOBIKE, IKEv2 always floats to port 4500 starting from the second

exchange. Some implementations don't like this behavior, hence it can be

disabled.

Charon by default uses the normal retransmission mechanism and timeouts to

Since 5.4.0, if both peers support RFC 7427 ("Signature Authentication

authentication may be configured. To do so use <literal>ike:</literal>
|

followed by a trust chain signature scheme constraint (see description
|
|
of the <option>remote</option> section's <option>auth</option>
|
|
keyword). For example, with <literal>ike:pubkey-sha384-sha256</literal>
|
|
a public key signature scheme with either SHA-384 or SHA-256 would get
|
|
used for authentication, in that order and depending on the hash
|
|
algorithms supported by the peer. If no specific hash algorithms are
|
|
configured, the default is to prefer an algorithm that matches or
|
|
exceeds the strength of the signature key. If no constraints with
|
|
<literal>ike:</literal> prefix are configured any signature scheme
|
|
constraint (without <literal>ike:</literal> prefix) will also apply to
|
|
IKEv2 authentication, unless this is disabled in

If a DH group is specified, CHILD_SA/Quick Mode rekeying and initial

any DH group specified here will only apply when the CHILD_SA is later

rekeyed or is created with a separate CREATE_CHILD_SA exchange. A

proposal mismatch might, therefore, not immediately be noticed when the

A protocol/port selector is surrounded by opening and closing square

When IKEv1 is used only the first selector is interpreted, except if the

Cisco Unity extension plugin is used. This is due to a limitation of the

IKEv1 protocol, which only allows a single pair of selectors per

CHILD_SA. So to tunnel traffic matched by several pairs of selectors when

|
using IKEv1 several children (CHILD_SAs) have to be defined that cover

the selectors. The IKE daemon uses traffic selector narrowing for IKEv1,

the same way it is standardized and implemented for IKEv2. However, this

|
may lead to problems with other implementations. To avoid that, configure

identical selectors in such scenarios.
