[Netkit.users] TAP interface & masquerade

[Cyrille OLIVIER]

Hi,

I try to setup a TAP interface.

vstart r1 --con0=this --eth0=tap,10.0.0.2,10.0.0.3 => OK, r1 boot successfully.

So, inside r1: eth0=10.0.0.3/24

The host PC has a real network-interface eth0=10.0.0.2/24

To reach internet, the next-hop is the 10.0.0.1/24 in another PC.

 

In the host PC, ping 10.0.0.1 is OK. ping 10.0.0.3 is OK.

Inside r1 vm: ping 10.0.0.2 is OK. but ping 10.0.0.1 is NOK :(

 

In the host PC, I check: 

- /proc/sys/net/ip4/ip_forward is 1 : OK

- iptables -L does not display the masquerading in postrouting chain(result of 'iptables -t nat -A POSTROUTING -j MASQUERADE') but its seems OK.

 

Any idea why ping from VM to external gw is NOK ?

 

Thanks,

Best regards to all,

Cyrille
