[tor-talk] Tor disconnects and must be restarted while using OpenVPN

[ef2k]

Hi,
I'm trying to connect to an OpenVPN server for my general internet 
traffic but keep Tor for DNS lookups and as a SOCKS5 proxy for a few 
applications.

I connect to my OpenVPN server and everything works as expected, but 
after 30-40 seconds (seems to depend on number of requests to Tor?), all 
Tor requests just time out (incl. Tor DNS requests) and it's unusable. 
If I restart Tor with "service tor restart" then it will work again for 
another 30-40 seconds before it disconnects again.
Nothing is shown in Tor's log located at /var/log/tor/log about this.

My iptables rules are:
iptables -A INPUT -i lo -j ACCEPT
iptables -A OUTPUT -o lo -j ACCEPT
iptables -A OUTPUT -d 255.255.255.255 -j ACCEPT
iptables -A INPUT -s 255.255.255.255 -j ACCEPT
iptables -A FORWARD -i wlan+ -o tun+ -j ACCEPT
iptables -A FORWARD -i tun+ -o wlan+ -j ACCEPT
iptables -t nat -A POSTROUTING -o tun+ -j MASQUERADE
iptables -A OUTPUT -o wlan+ ! -d *VPNIP* -j DROP

Hope someone can help to resolve this, it's very frustrating. Thanks in 
advance.
