I recently came across this router and installed OpenWRT on it - however I am failing to configure it the way I want it to.
Maybe you guys can help me out.
The following is the actual situation:
- I have a cable router, which I can't replace
- So I purchased this router to mainly serve the purpose for a separate LAN with having a permanent OpenVPN connection to one of my servers within a datacenter on which I mainly do my work
I tried to setup the WRT3200ACM in two ways:
- WAN port uplink from cable router:
I simply plugged in a cable from my cable router to the WAN port of the WRT3200ACM and use the cable router as "uplink". Furthermore I configured the router to be in another (non-default) network: 10.10.20.0/24. This works perfectly fine, until I want to configure the OpenVPN connection - the OpenVPN connection works just fine from the router itself, however it does not work from any connecting PC. Even worse, I can't seem to resolve/ping anything from a client - from the router itself it works perfectly fine (resolving DNS and connecting to any servers within the data center from the router itself).
As I couldn't make it work, I thought I'll give it a shot while using the router as a bridge
2. Uplink from LAN port
I followed basically the same approach as above, but this time I disabled WAN completely and got my uplink via LAN. Furthermore I didn't put the router in a separate subnet, as it should only "extend" the current network. However I had the same results: OpenVPN connection works fine from the router itself, from a client not.
I used the following guides to set it up:
1 + 2: https://openwrt.org/docs/guide-user/network/wifi/bridgedap
My goal is to have the following setup:
Have the router in a separate subnet (10.10.20.0/24) and route all traffic (from both WIFI and LAN), which are not in the local subnets (10.10.20.0/24 (wrt3200acm) and 192.168.0.0/24 (cable router)) through the openvpn connection.
I hope I could state my point properly.
If anything is unclear, please ask - I'd be happy to get a hint to the correct direction.
Thank you very much!
