I need to allow protocols 50 & 51 (AH & ESP) through our ASA 5505 Firewall so that our Nortel VPN Client will connect to a remote network.
Can you tell me how I go about this please, are there inspect rules I can add?
There are also UDP ports I need to allow, but I believe UDP is allowed anyway by the implicit allow rule?
Does this implict outgoing rule "allow all IP to any less secure network" on the ASA only include UDP and TCP? can someone confirm this please.
