Re: [Openvpn-users] Strange problem...

OK, if it's a firewall issue, how do I fix it?

The OpenVPN FAQ says to enter these commands which I have done:

# Allow TUN interface connections to OpenVPN server

iptables -A INPUT -i tun+ -j ACCEPT

# Allow TUN interface connections to be forwarded through other interfaces iptables -A FORWARD -i tun+ -j ACCEPT

# Allow TAP interface connections to OpenVPN server

iptables -A INPUT -i tap+ -j ACCEPT

# Allow TAP interface connections to be forwarded through other interfaces iptables -A FORWARD -i tap+ -j ACCEPT

There is no hardware firewall in the way that I know of. I wouldn't expect to get an 'Operation not permitted' message if it was a hardware firewall either.

Thanks in advance for the help!

You do have a firewall issue on this system
