Public bug reported: Dear all. I have a problem: my ssh tunnel works fine for a while (this time varies from minutes to hours) and then just stops to forward packets in one direction. I tried to google this problem, but didn't find the solution. Detailed description: I have Gutsy on both machines. Machine A - is client, machine B - server. My /etc/network/interfaces files looks like this: Machine A: iface tun0 inet static pre-up echo 1 > /proc/sys/net/ipv4/ip_forward pre-up ssh -f -w 0:0 machine_b_ip_address 'ifdown tun0; ifup tun0' pre-up sleep 5 address 10.0.0.1 pointopoint 10.0.0.2 netmask 255.255.255.0 up route add -net 192.168.1.0 netmask 255.255.255.0 gw 10.0.0.2 tun0 down route del -net 192.168.1.0 netmask 255.255.255.0 gw 10.0.0.2 tun0 Machine B: iface tun0 inet static pre-up echo 1 > /proc/sys/net/ipv4/ip_forward pre-up sleep 5 address 10.0.0.2 pointopoint 10.0.0.1 netmask 255.255.255.0 up route add -net 10.88.171.0 netmask 255.255.255.0 gw 10.0.0.1 tun0 down route del -net 10.88.171.0 netmask 255.255.255.0 gw 10.0.0.1 tun0 I start tunnel using "sudo ifup tun0". Then everything is working for some time. When it stops to work, I found out, that tunnel does not forward traffic from machine B to machine A, while traffic from machine A to machine B is forwarded correctly. Network device tun0 on machine B just stops transmitting the data. Also I noted, that it happens more frequently, while transmitting big amount of data. Please, help me to fix that. It's really borring to restart tunnel so often.
