 |
Hi
I'd like to use my NetGear WNDR3700v2 running DD-WRT as DHCP,DNS and gateway for my internal network, and another wired dial-up router as internet access for WNDR3700v2.
I disabled WNDR3700v2 WAN function, change WNDR3700v2 to route mode, and set its ip to 192.168.1.2, gateway 192.168.1.1(the wired dial-up router), PC clients gateway set to 192.168.1.2
here is what I got
before OpenVPN

Then, all my internal traffic goes to OpenVPN interface, that's not what I expected.
I would like have all traffic default goes to 192.168.1.1, and if only client need to access specified IP(like 198.18.99.1) goes to 198.18.96.1.
I tried to run command "route del default", but this command remove the default br0 route, and default tun1 still exists.
Please help on this routing setup, appreciate. |
