Problem with WAN to LAN port
Hi,
I'm struggling a bit with routing and NAT. I have the following setup.
I have no way to alter configurations on Router B or C. However.. PC1 can sucessfully ping WAN IP of Router D and PC2 can successfully ping the WAN port of router A. However PC1 cannot ping Router D's LAN address nor can PC2 ping Router A's LAN address. So I know traffic can travel from Router A to D.
I have turned OFF all firewall options on Router A and D. I have seen the post about WAN ports not sending info through to the LAN port and suggestions about NAT as well.
When I have tried to use NAT on Router A and D with the following setup...
I still can't seem to get the WAN port on Router A to pass traffic to it's own LAN port and the same on Router D. I've tried tinkering with the static routes too and have had to factory reset the routers as result as it stopped me getting into them.
Can anyone kindly advise where I am going wrong here, I'm at the head/wall interface stage. Thanks
