We're trying to receive a packet into a buffer which isn't large enough for it. Try hacking the tun_mainloop() function in mainloop.c, around line 59, to use a hardcoded 1500 instead of vpninfo->ip_info.mtu as the packet size. I bet you see the issues go away. We need to work out how to tell Windows what the MTU is. Preferably without Windows needing to reboot to apply the change :) -- dwmw2 -------------- next part -------------- A non-text attachment was scrubbed...
