Hi,

Correct me if I am wrong. Check your firewall log... If I remember correctly, although your squid machine initiates the connection on a semi-ramdom port, the samba server replies to it, with a specific source-port. If so you can add a custom rule allowing all connections from that specific source port and from the samba server.

It's a random port from the squid/firewall machine that goes to port 137 (I checked) on the samba-server and the response is blocked/dropped.
This is also what I stated. What I asked you to confirm is that if the response from the samba-server has a specific source port, mentioned in the firewall log as STP.
So, you have to look in your firewall log for something like SRC=<samba-server IP> PROTO=UDP SPT=<specific port>

If you still cannot advance, please continue with showing the firewall log file. There has to be a solution...

I'll have to check how I can make such a custom rule. Never done this before.
Thanks.
