Package: racoon
Version: 1:0.8.0-14
Severity: important

When enabling ipcomp with the following configuration in
/etc/ipsec-tools.conf:
spdadd 192.168.5.95 192.168.5.94 any -P out ipsec
        ipcomp/transport//use
        esp/transport//require
        ah/transport//require;
spdadd 192.168.5.95 192.168.5.94 any -P in ipsec
        ipcomp/transport//use
        esp/transport//require
        ah/transport//require;

Now when executing the following line:
root@ipsec1:~# ping -c 4 192.168.5.95
PING 192.168.5.95 (192.168.5.95) 56(84) bytes of data.
^C
--- 192.168.5.95 ping statistics ---
4 packets transmitted, 0 received, 100% packet loss, time 3000ms

Now increasing the size of the ping packet:
root@ipsec1:~# ping -c 4 -s 300 192.168.5.95
PING 192.168.5.95 (192.168.5.95) 300(328) bytes of data.
308 bytes from 192.168.5.95: icmp_req=1 ttl=64 time=0.955 ms
308 bytes from 192.168.5.95: icmp_req=2 ttl=64 time=1.10 ms
308 bytes from 192.168.5.95: icmp_req=3 ttl=64 time=0.916 ms
308 bytes from 192.168.5.95: icmp_req=4 ttl=64 time=0.925 ms

--- 192.168.5.95 ping statistics ---
4 packets transmitted, 4 received, 0% packet loss, time 3007ms
rtt min/avg/max/mdev = 0.916/0.976/1.108/0.077 ms

I have also tested this without racoon, by putting the ah, esp and
ipcomp information in /etc/ipsec-tools.conf, then I am able to ping also
with small packets.

Looking at tcpdump, I see that for small packets no compression is
applied, that's ok according to bug #301466. I do not understand why the
traffic isn't sent back.

If you need more information, please ask.
