I am trying to set up a new VPN connection between Site A and Site B.
It passes phase one but throws up an error at phase two. I will attach the error message.
Site A's firewall currently has another VPN on it working away fine so I suspect the problem lies on Site B's config.
Thanks in advance
PFS is not matching.
Site A: you have "crypto map outside_map 2 set pfs group1"
Site B: you have "crypto map outside_map 4 set pfs" ---> which default to pfs group 2
Change either one to match each other.
Hope that resolves the issue.
