Aggressive mod dont connect… problem don't solve..

cmb

Yes that's a problem in racoon, e.g. the 2.1.x side. In that circumstance, you won't be able to use aggressive mode (at least until you upgrade the other end to 2.2). Main is preferable anyway.

ondokuz

thank you very much. Which do you recommend ? Which is more secure? aggressive or main ?
best regards.

cmb

Main is always best unless it's not an option for some reason (like in some mobile IPsec scenarios). For site to site VPNs, you should always use main mode, unless you're connecting to some odd third party device that doesn't support it.

Hi,
I can't get my tunnels connected anymore since build from 7th of Jan.
before it was working good with Aggressive Mode, but even switching to Main mode didn't help.
I have 2 phase 2 policies.
The other side of course is a pfsense 2.1.5
I'm using Main, AES/256, with SHA, DH Key2 with NAT-T enabled.
Phase2: ESP, AES(auto) with SHA1, MD5, PFS key2

Updated to build 10th of Jan.

Errors on the 2.1.5:

You phase1 does not match.
Your ips might have changed?

my pfsense 2.2 configuration.

working all snapshots….

my pfsense 2.1.5 configuration

tracer

This is pretty much my config, except that i have Phase 2 MD5 enabled as well.
And DPD is disabled right now, but was enabled before, with no success.

ondokuz

Make sure you're on the latest snapshot, some things were in flux with IPsec this past week which could affect what you're doing. If it's still an issue on the latest snapshot, please start a new thread on this board, as that's a separate issue from OP's.

Thanks Chris,
will updated and report back in a new thread.
