Asus rt-n66u: strange route issue after enable openvpn

[johnqhu]

I bought a rt-n66u and installed Merlin 378.55 firmware. Then I enabled the openvpn server1. After the vpn server is enabled. I found I can't access some website. Such as 14.17.32.229.

I checked the route table. It's

admin@RT-N66U-6BA0:/tmp/home/root# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
171.214.206.1 * 255.255.255.255 UH 0 0 0 ppp0
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
192.168.0.0 * 255.255.255.0 U 0 0 0 br0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
8.0.0.0 * 248.0.0.0 U 0 0 0 tun21
default 171.214.206.1 0.0.0.0 UG 0 0 0 ppp0
default 192.168.1.1 0.0.0.0 UG 1 0 0 eth0

I think it's "8.0.0.0/248.0.0.0" of the vpn interface that make me can't access 14.17.32.229.

Then I disabled the vpn server and the "8.0.0.0/248.0.0.0" rule gone and everything is OK.

So how can I fix it? I need the vpn server. Thanks!

Sorry, I should post it in Merlin support forum. Could anybody delete this thread? I'll re-post it in Merlin forum.
