I have a Sophos SG230 running UTM9 (version 9.605-1) I have 4 interfaces enabled Exernal (WAN), VPN, Internal and InternalVLAN88,
I am having problems getting from internal (192.168.10.1/24) to internalVLAN88 (192.168.88.254/24), but not the other way around?
I have tried with RDP (this is what it need working), from InternalVLAN88 I can access a host on internal (from 192.168.88.102 to 192.168.10.102) all good, but going the other way (from 192.168.10.102 to 192.168.88.102) no luck.
I get these lines in the firewall log (my rule allowing RDP tcp/udp 3389 from and to 192.168.10.102 and 192.168.88.102 is number 5) Seems like traffic from internal to internalVLAN88 finds way to the net but gets lost on the way back?
Any suggestions what I am missing
