GRE Tunnel through ASA5505

[jcmartin]

I'm trying to open a GRE tunnel (protocol 47) through an ASA5505 running PAT to an ISP. Getting the following error: %ASA-3-305006: regular translation creation failed for protocol 47 src inside:192.168.1.19 dst outside:xxx.xxx.xxx.xxx. Listed bugs relating to this error do not seem to relate to the issue at hand. ASA is running version 8.0(4).

if it's pptp,inspect pptp would help.

if not,you would need static nat as gre does not have any ports ( hence not pat ).

That was almost embarassingly easy. Thanks for the help.
