Having issues with consultant on the inside trying to VPN to his office Sonicwall. I verified it works on an outside connection and I see his headend IP being denied in my ASA log. His Sonicwall client never gets an IP. It appears stuck at the "connecting" phase.
I already have an Outside access in ACL, can I just add the line below?
access-list Outside_access_in extended permit udp host xx.xxx.xx.xxx any eq isakmp
...or is there more to it.
