Openvpn with a nat 4 or 5 clicks and no internet

Post by jonplanetveo » Wed Jan 12, 2011 12:43 pm

Hello everybody,

I have a dedicated server used as a web vpn.
So on it, I installed openvpn and a nat to redirect the subnet to eth0
I can access to pages, pretty fastly, but after 4 or 5 clicks the page doesn't load anymore.
When I try to ping the vpn gateway, it responds so I guess it's coming form the nat.

I will post later my configuration, but If someone can already help me, it will be great

Hello,

Also post your client and server logs (verb 4 preferred).

Post by jonplanetveo » Thu Jan 13, 2011 7:33 am

sorry, my mistake, the port is 1194 and the connection between the server and the client is working.
But after a 1 or 2 mins I'm still connected on the vpn but no more Internet.

My local network ip address is 192.168.5.X

Post by krzee » Thu Jan 13, 2011 8:52 am

during those 1-2 minutes, if you go to http://secure-computing.net/ip.php does it show the vpn server ip?
if so, try adding bypass-dhcp after you redirect-gateway
also, when the vpn goes down do you want to stay connected to the internet without the vpn? if so add def1 after redirect-gateway

see the full list of options in the manual:

Post by jonplanetveo » Thu Jan 13, 2011 9:12 am

I add

Code: Select all

push "redirect-gateway bypass-dhcp def1"
and the result is the same.
During this 1 or 2 mins my public ip becomes the VPN ip and I can access to websites normally blocked.

This is my iptable configuration

Code: Select all

iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
