[Question #231116]: no ping with remote server

 

New question #231116 on rohc:
https://answers.launchpad.net/rohc/+question/231116

hi, 
i have setup a scenario :
- 2 VM with centos 6.3 
- rohc 1.6
- iprohc0.6 
followed the instructions on wiki : http://rohc-lib.org/wiki/doku.php?id=iprohc-run
both vm are in same network : 
- server: 192.168.1.100
- client : 192.168.1.99
everything works fine : connection, ping, i see traces in log

now , i move the server VM to a remote public location with public IP : x.x.x.x
the client remains same (behind a ADSL modem)
i reconnect : link is connected , ping between client and x.x.x.x works 
no firewall is activated
but i cannot ping the tunnel : 192.168.42.1 from client 
ping just freeze : no response.

what can be the problem?

server log :
