Hello all,
In a twist I have set up a web proxy on a rb192.
I have bridged eth 2-5 as a wan hub and eth 6-9 as a Lan Hub with eth1 as GW.
users in the lan can browse he internet etc but they cannot reach the mail server which is connected to the eth bridge 2-5.
What could be the problem? have tried arp settings but no change.

regards
LM
