Firewall not allowing SMTP through

  • If this is not the right area to ask this question, please direct me to the appropriate location. I originally had an old PC tower running pfSense and recently bought a StrongBochs to import the settings from that PC tower into the StrongBochs using the backup/recover under diagnostics. Now I can not connect to SMTP using PuTTY since I did this. The old PC had 3 NICs (LAN,WAN,DMZ). The StrongBochs only has 2 NICs.

  • I did not originally set up the PC I am bringing the settings from. I'm thinking that has to do with the DMZ maybe? The DMZ had an IP of

  • I assume you renumbered the server that used to be in the DMZ?  If so, you need to change the port forwards and such (or more easily, just change the LAN IP from a /29 to a /28?)  But the server likely is talking to the address, so you will need to change one or the other?

  • I will try to change the LANs mask and IP to

  • Thank you danswartz. That fixed my problem.
