What happens if you remove the -s and -d options ?
No SNAT/MASQUERADE on the tunnel ?
Could it be that the tunnel packets are dropped on the WAN interface ?
What kind of tunnel protocol is it ?
> The packets can't gain access to tunnel tcpdump say me.
Can you explain this please ? My tcpdump only shows packets which enter
and leave a network interface, it does not tell anything about getting
access or not.
