Routing problem with OpenVPN on Linux

[AMG]

I have an Asus RT-N16 router with DD-WRT on it. The IP of this router is 192.168.1.1. I have a Linux server with OpenVPN on it. The IP of the Linux server is 192.168.1.99. I have OpenVPN setup for routing not bridging. The IP address for tun0 in Linux is 192.168.2.1. When connected on the VPN from my Windows client I can access anything that is on the Linux server (192.168.1.99) but I cannot access other servers on my network (most importantly anything on 192.168.1.xxx). I think I somehow need to tell my router that anything that goes to 192.168.2.xxx to route through my VPN IP? I am kind of lost, so I finally decided to post here. Thanks for your help!

I have also tried adding a route from the DD-WRT web UI under "Advanced Routing" to route all traffic in 192.168.2.0 to the gateway 192.168.1.99 (the IP of the Linux server where OpenVPN is running)

you may need the section "ROUTES TO ADD OUTSIDE OPENVPN"
but i can not guarantee that part is the problem, since you said you did add a route to the router.

I should have updated this thread.
I did in fact fix it and it's been working perfectly.

I added this line to my server configuration file.

route 192.168.201.0 255.255.255.0

Oh, I also switched from 192.168.1.0 and 192.168.2.0 to 192.168.200.0 and 192.168.201.0 So basically adding the route line. I already had the line:
push "route 192.168.200.0 255.255.255.0"
present, but I also needed the other.
thanks.
