My topology is as the picture above. I've configure to allow incoming traffic into each pfSense interface, include 3 LAN and 1 WAN. Ex: I can ping from DC to pfSense interface in the same network. I used default Manual Outbound NAT rule generation but still can't ping from inside network to outside and receive this message "PING: transmit failed. General failure." Help me fixing this please.
Okay, by default the first LAN connection should be able to ping from the LAN to WAN (Outbound rules) but the rest of the LAN interfaces do not have rules automatically created: You will need to add rules under Firewall > Rules > [LAN*] and Firewall > NAT > Outbound.
Clarifying the LAN rules again, you will need a rule to say certain traffic is allowed in and out.
I do not know exactly what you have configured - IP address wise - from your original post.
If you require further assistance, could you send a screen-shot of the above tabs.
I hope the above helps.
Kind regards,
Andre Morton
