Can't ping the vpn server trough the tunnel #49

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Connect to the VPN and can't ping the VPN server.  I can see phone is 
connected to the server and ifconfig on the phone shows the tun adapter 
received an IP address but I can ping the server no can I ping the phone from 
the server.  I don't get an arp entry either on the phone or the server.

What is the expected output? What do you see instead?
Should be able to ping the server.

What version of the product are you using?
OpenVPN-Settings-0.4.7.apk and OpenVPN-Installer-0.2.3.apk

Which Android phone are you using?
HD2

Which firmware version are you using?
2.2

Please provide any additional information below.
Basically copied the config/directory from a working linux computer on the 
sdcard.  The config works for the laptop but not the phone.  I can attach the 
server/client config if needed.  Also, I connect through a http proxy...

This is invalid.  I have a dns issue.  I can ping through the VPN tunnel.

I discovered that my problem was related to the firewall (iptables) on my 
DD-WRT based router, that hosts my OpenVPN server.

Hello, I have the same problem and it is not due to a firewall. Please fix it.
