This is similar to my setup, but instead of just a single pc being accessible from the wan, I want the whole range.
pretty sure it is something to do with our WAN firewall settings not allowing IN traffic to the LAN, I just cant figure out the commands needed to set this up.
in my situation I am setting the edge routers up like so
eth0 - "WAN" in this case it is connecting to 192.168.1.0/24 at the main office
eth1 - Disabled
eth2 - LAN in this case it is 192.168.2.0/24 with DHCP from 2.100 - 2.200
I can ping anything from 192.168.2.0/24 in the 192.168.1.0/24 subnet, but I can not however ping anything from 192.168.1.0/24 in the 192.168.2.0/24 subnet.
Like I said, I think both our problems would be resolved if we could pass the requests from WAN to LAN but it seems like we are dropping all requests for anything from outside of the 192.168.2.0/24 range.
hopefully bumping this post will get someone with a better mind for the edgerouter CLI to see it, and help us
