Only tunnel certain applications via OpenVPN
- by jinjin
Hi,
I've purchased a VPN solution, it works correctly when I have "redirect-gateway def1" in the configuration file (routing all traffic through the VPN).
However when I remove that line from the configuration file, I am still able to ping-out of the machine (ping -I tap0), however I cannot ping the IP assigned to the machine (it's a public ip), i get the error: Destination Host Unreachable.
I only want to have certain applications sending traffic through the VPN tunnel (eg: ZNC, irssi), all of which i can select which IP they use. However they can't recieve any data, making the tunnel essentially useless to me when disabling redirect-gateway.
Any ideas on how to allow specific applications use the tunnel, without of forcing everything to go through it?
My configuration file is as follows:
dev tap
remote #.#.#.#
float #.#.#.#
port 5129
comp-lzo
ifconfig #.#.#.# 255.255.255.128
route-gateway #.#.#.#
#redirect-gateway def1
secret key.txt
cipher AES-128-CBC
The output of ifconfig -a when the tunnel is connected:
tap0 Link encap:Ethernet HWaddr 00:ff:47:d3:6d:f3
inet addr:#.#.#.# Bcast:#.#.#.# Mask:255.255.255.255
inet6 addr: <snip> Scope:Link

EDIT: the Bcast:#.#.#.# (ifconfig) is different from route-gateway #.#.#.# (openvpn) if that makes any difference.
