Hi all,

I'm having problem connecting to my router wrt54g running openvpn w/v23 sp1 final built 05/30 vpn. I was able to connect from inside my LAN, but cannot connect from outside WAN. I've attached a server and client config and openvpn log below. Appreciate any help

Server config

iptables -I INPUT 1 -p tcp --dport 443 -j ACCEPT
openvpn --mktun --dev tap0
brctl addif br0 tap0
ifconfig tap0 0.0.0.0 promisc up
echo "
-----BEGIN OpenVPN Static key V1-----
...INSERT YOUR OWN CONTENT HERE...
-----END OpenVPN Static key V1-----
" > /tmp/static.key
ln -s /usr/sbin/openvpn /tmp/myvpn
/tmp/myvpn --dev tap0 --secret /tmp/static.key --comp-lzo --port 443 --proto tcp-server --verb 3 --daemon

Client config

remote dyndns.homeip.net

port 443
dev tap

secret static.key
proto tcp-client
comp-lzo

##route-gateway 192.168.1.1
##redirect-gateway

What happens when you telnet to port 443 from the outside? On windows:
telnet server.ip.com 443

Does it connect and give you a blinking cursor or do you get a connection failure?

I got it working now. It was a typo mistake. Being a Linux newbie, I didn't realized the commands all had to be in "1" line.

Once connected from the WAN, I'm able to ping my router (192.168.1.1), but unable to connect via a browser or see any of my other clients.

Thanks for responding kevank

I had this problem and wasn't able to telnet (good troubleshooting start!). I just disabled the SPI firewall on the "server" WRT and it connected. Is this the proper way to go? I'm sort of following the Wiki for a static key WRT but I also used your info because the Wiki isn't clear on the WRT as the client in that setup.
