Hello- I'm trying to VPN to my box at home from campus. I get in, but have some strange problems once I'm connected. A little background: OpenVPN is running on a box behind my iptables-based firwall, all systems involved are linux. The OpenVPN box is bridging the connection to two pre-existing Ethernet connections, so everything is utilizing Tap rather than TUN. The bridging box is running OpenVPN 1.4.3 and kernel 2.4.20. The laptop is running OpenVPN 1.4.2 and kernel 2.6.0-test6. I set up the VPN connection on both ends, it connected, and I added tap0 to the br0 bridge. After perhaps 15-20 seconds of running pings through the bridge to let it figure everything out, packets were going through without any problems... ICMP packets, anyway. I was then able to ssh about, to the bridge box and then to the firewall through the bridge box, as if my laptop were plugged in to the LAN itself. Perfect, I thought. I then opened up my mail client and tried to connect to my IMAP server (running on the 'firewall') - it would make an initial connection, but would hang before any data went accross. I then fired up slrn (leafnode is also running on the 'firewall') ... it connected, downloaded new groups, got a new message count, but then wouldn't go any further, it just hung until the connection timed out. None of the interfaces involved, eth0, br0, or tap0 on the bridged box... and tap0 on the laptop... showed any dropped packets or errors. The protocols just wouldn't work. I tried, then, running /sbin/ifconfig from the firewall/server and the SSH connection froze halfway through printing the MAC address. Any idea what might be up with this? MTU problem, maybe? I don't know what the symptoms of that would be... or how it might relate to the tap0 interface being bridged.... I'm going to be back trying to get it working again tomorrow if anybody has any hints! :-) -- Rob | If not safe, Jabber: athlonrob at axpr.net | one can never be free. ____________________________________________ Openvpn-users mailing list Openvpn-users@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/openvpn-users |
