Can't you just do an "ip change tunl0 ttl 64" afterwards?

get answered from that interface?
It appears it works fine if I create the tunnel with:
/sbin/ifconfig tunl0 44.137.24.1 netmask 255.255.255.255 up
/sbin/route add -net 0.0.0.0 netmask 0.0.0.0 metric 128 tunl0
/sbin/route add -net 44.0.0.0/8 gw $GATEWAY tunl0
/sbin/route del default tunl0
But then I cannot set ttl to 64 (for traceroute).
