I am trying to setup a site to site VPN between ASA 5510 and SSG 140 firewall. ASA end of the VPN is having dynamic public IP address. I tried sending hostname as peer identity on ASA by changing the IKE parameter setting but SSG somehow is not able to match the hostname of remote peer and reporting remote as unrecognized peer. Does someone has experience in setting up site 2 site VPN in similar setup?
