DPD retransmission attempts for IKEv2

General questions

1

The DPD retry/retransmission can take up to around 2 minutes for IKEv2. Strongswan already exposes configurables for charon retransmision:

https://docs.strongswan.org/docs/latest/config/retransmission.html

Does VyOS provide any way to configure these too?

DPD interval/timeout is exposed in ike-group DPD settings.

IKE retransmission settings are not currently exposed in CLI. Feel free to make a feature request on https://vyos.dev for it.
