GRE Issues

sprocket10 · ‎01-30-2018

GRE was running across 2 Linux systems between sites. The VPN was between an ASA and WatchGuard with no issues. Recently we replaced the WatchGuard with an ASA, and the GRE tunnel is now only working in one direction. I have compared both ASAs and cant spot an obvious issue.

Then you have to check your routing and ACL configuration for the GRE tunnel.

For more investigation please share running configuration of both ASA.

Hi

Check the ACLs to know if they have the same permissions.
