Hi,

I just configured 2 ER605 in 2 different office locations. I managed to get the LAN-to-LAN IPSec to connect appropriately after putting each router as the DMZ device to ensure all ports/traffic was getting forwarded to it on both sides. I can ping the LAN IP address from the other side with no issues. However, I can't get any other traffic to be reached between the two LANs. Any ideas of what I might be missing here?

Those 2 ER605 are replacing older Netgear routers, which also had an Office-to-Office IPSec VPN setup with the same Internet gateways (Comcast), so it feels very puzzling why it is not working.

Thank you in advance for any suggestions.
