IPSEC PFsense - Unifi - Blocked SMB traffic

Networking & Firewalls
1

I have a tunnel between pfsense netgate6100 and unifi gateway. Traffic is going through to the subnets on each end, but SMB traffic is not being allowed on the subnet on the netgate traffic. I have a firewall rule wide open allowing all traffic from the 2 subnets on each site of the tunnel, but can’t connect windows shares. DNS, RDP, icmp traffic work.

Any suggestions?

It’s probably not the firewall blocking but a setting on the host running SMB.

Turns out you are on the right track, turns out the two domain controllers in that site subnet were out of sync and denying access based on trust failures.

Thanks
