New problem arise after i

pratik-koshiya · ‎04-17-2014

I am configuring site to site between fortigate and asa. I am not sure if I am making any mistake in configuration or not. I got information for fortigate and based on that I am implementing peer config in asa. Below is my config.

Can anyone suggest me any change or re-direct me for what to check on asa side?

Robert Falconer · ‎04-17-2014

Have you run any debugs when trying to make the connection?

I've had issues with PFS on tunnels between vendors. Have you tried disabling PFS on both ends?

Robert Falconer · ‎04-17-2014

Do you have any other tunnels configured on this ASA? You have a lot of parameters defined for transform sets, authentication types, hash and encryption.

What did the Fortigate admin provide you?

PFS is currently causing me issues between vendors. You have PFS configured everywhere which could be causing a problem.

pratik-koshiya · ‎04-17-2014

Yes I have another remote IPSec tunnel configured on ASA through which I am accessing ASA remotely. Yes we have PFS configured on both side with group 2. Fortigate admin has provided me peer ip, phase1 and phase2 config with PSK and PFS that we used.

Richard Burts · ‎04-17-2014

It looks like you are encountering the problem in the ISAKMP phase 1 negotiation. I would start by re-configuring the shared key (and probably ask the administrator of the fortigate to do the same. If it still does not work then I would try running debug for isakmp on your side and see if it tells you a bit more about where the problem is.

I am setting up site to site again. I will update once i configured it.

pratik-koshiya · ‎04-18-2014

New problem arise after i removed tunnel and choose internal DNS. I saw that tunnel comes up from both ends. I can ping IP but i cannot use any internal services or RDP services. Can you tell me which ACL i should implement now?

I have already allow ACL for IP service between both ends.
