IPSec site to site tunneling not able to see computers on remote side

Hi NeutralSt8,

have you ticked automatic firewall rules?

If you have ticked can you enable the logging for this rule and show us the log?

Best Regards
DKKDG

Thanks for the reply. Here is the log from the initiator side of the tunnel. Let me know if you need the responder side as well.

I have edited the actual IP's with search and replace but if you need the actual details, I can forward the actual log file that I created. I noticed that there appears to be a number of "whack messages" but I am not sure what may have initiated those comments LOL.

Hi NeutralSt8,

actually i meant the firewall log and not the IPSec log.

But when the IPSec tunnel is established and no traffic is passing through try to build your own policy on both gateways.

Keep in mind both side must use the same parameters in this policy.

If you have your new policy change it in your IPSec connections.

I've never seen any VPN issue here that required having debug enabled to figure out the solution to the problem, but don't bother posting with debug off - DKKDG's right that the solution is elsewhere.  Do you have 'Automatic firewall rules' selected in the IPsec Connection on both sides?  Does #2.3 in Rulz help?

Cheers - Bob

Auto firewall is on and strict routing is not in use - on both sides

I did not change any of the default AES-256 details on either end and had followed the example in the link.

I am still able to remote desktop to the listening side of the site-to-site using the SSL VPN client connection that I had been using before.

However, if I disconnect the SSL client and enable the IPSec site to site, I can no longer ping any of the remote computers.

Any ideas on where the problem may be? Could they be in the Firewall rules and if so, why would it affect the site-to-site but not the SSL client?

Hi NeutralST8,

did you build a new policy as i proposed?

Best Regards
DKKDG

Yes I created a new policy called MyOwn Policy on both routers and the same problem. I can connect but can traverse the network at the listening end. :-(

Sorry meant "can't" not "can"

Hi NeutralSt8,

do you have matches on both firewall logs?

The 2 external addresses (184.xxx.xxx.xx2 and 24.xxx.xxx.xx1) are correct as well as both the declared internal networks.

Not sure what I should be looking for in the firewall logs.

Sorry a bit of a amateur with the debugging. What should I be looking for? When I attempt RDP to my remote server, no entries appear for the IP that I am trying to query.

BTW thanks for the follow up replies

Hi NeutralSt8,

the IPSec log is not needed.
The packetfilter log ist what i meant.
