Alright, I now am able to ping a device on Router B from a device on Router A, but I’m still not able to ping a device on Router A from a device on Router B.
Here’s the firewall settings for Router B:
lan zone:
Input: accept
Output: accept
Forward: accept
Masquerading: false (unchecked)
MSS clamping: false (unchecked)
Covered Networks: lan
Allow forward to destination zones: wan, wan6, wwan
Allow forward from source zones: wan, wan6, wwan
wan zone:
Input: accept
Output: accept
Forward: accept
Masquerading: false (unchecked)
MSS clamping: true (checked)
Covered Networks: wan, wan6, wwan
Allow forward to destination zones: lan
Allow forward from source zones: lan
EDIT:
Scratch that! apparently it is working. I could’ve sworn that I checked the ping. Maybe I subconciously applied something else.
