Ive got a routing problem that has been perplexing me for months, wonder if anyone can help. I am a relative MT Newbie
About my MT and network environment:
- Running 6.43 (Stable)
- Eth 9 is LAN with networks 192.168.1.0 - 192.168.6.0
- Eth6 is WAN to ISP
- Eth1 has a non-external but routable IP of xxx.xxx.xxx.233/29 and is ethernet connected to an ASUS RT87U wireless Router (see below)
The purpose of the RT87U is it does OVPN with a VPN service over UDP.
- The RT87U has a static WAN address of xxx.xxx.xxx.234 (incremental to the above) and does NAT for the 192.168.7.0 network. Note the xxx.xxx.xxx.233 address on eth1 on the MT serves as the Gateway for the ASUS router.
Pinging the 192.168.1.0 network from a client that is connected to the ASUS router i.e. (192.168.7.xxx), works without issue due to static routing on the ASUS router and a firewall rule on the MT allowing the xxx.xxx.xxx.234 address into my MT LAN (Eth9).
However, Pinging from the 192.168.1.0 network to any client on the ASUS Router does not work
Things I have tried:
- Obviously a static route entry in my MT:
a) xxx.xxx.xxx.232/29 GW:Eth1 pref source xxx.xxx.xxx.233
b) 192.168.7.0/24 GW:Eth1 no pref source
Pings I have tried to narrow down the problem:
- MT can ping xxx.xxx.xxx.234 (ASUS Router WAN Side)
- MT Cannot Ping xxx.xxx.xxx.233 eth1 port or gateway for Asus router
- MT can ping 192.168.7.0
Client on 192.168.1.0:
- Can Ping xxx.xxx.xxx.233 which is the MT eth1
- Cannot ping xxx.xxx.xxx.234
- Cannot ping 192.168.7.1
All firewalls have been disabled on the ASUS router
The reason I am doing all this is because the MT doesn’t do OVPN over UDP.
I hope this makes sense and would really appreciate any help
