While experimenting with the tun device I found that I was not able to receive packets on the tun interface (i.e. a udp listener for packets couldn't get the packets transmitted from the program which wrote to /dev/net/tun), if the source address of the packet was not equal to end point IP address of the tun pointopoint link. It seemed that internally, linux dropped a packet it saw on the tun interface (tcpdump on the tun interface shows the packet) because its source address didn't match the IP address of the pointopoint end host of the tun interface. My question is, can this check be disabled?
Just a wild guess: echo 0 >/proc/sys/net/ipv4/conf/tunX/rp_filter or echo 0 >/proc/sys/net/ipv4/conf/all/rp_filter c'ya sven -- The Internet treats censorship as a routing problem, and routes around it.
