Re: [Xen-users] can't get NAT to a VM on domU working

["Roberto Saccon" <rsaccon@xxxxxxxxx>]

I tried the script, but it still doesn't work, no idea why. But there are some packet flowing in both direcition when I snoop at the interface with tcpdump:


Client
--------
C:\Projects\workspace\test>ssh -p 9641 
myuser@xxxxxxxxx
=====> nothing happens, no login prompt

Server
---------
debian:/etc/network/if-up.d# tcpdump  port 9641
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
