Hi, I am trying to set up a site to site VPN between ASA 5520 and the check point firewall using the site to site VPN tunnel wizard from the ASDM. The checkpoint firewall is configured by the technicians on the third party site. we verified that all the configurations including pre-shared keys are the same. but it is not working.
How do I troubleshoot what the problem is? is there a way to force the tunnel to connect?
