Xen vif-route + vm's interconnection

Hi,
I have debian lenny with Xen + 2vms using vif-route script. Every machine has public IP address . Is this Xen-specific case or this is my misunderstanding of basic routing problems , but it seems that my machines can't reach each other. Here's the configuration ( ip a l & ip route for each host) Dom0 : root@dom0:~# ip a l | grep -B 2 1: eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:30:48:ba:25:3e brd ff:ff:ff:ff:ff:ff inet 23.23.195.111/24 brd 23.23.195.255 scope global eth0 -- 25: vif10.0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 32 link/ether fe:ff:ff:ff:ff:ff brd ff:ff:ff:ff:ff:ff inet 23.23.195.111/32 brd 23.255.255.255 scope global vif10.0 -- 26: vif11.0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 32 link/ether fe:ff:ff:ff:ff:ff brd ff:ff:ff:ff:ff:ff inet 23.23.195.111/32 brd 23.255.255.255 scope global vif11.0 -- 27: vif12.0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 32 link/ether fe:ff:ff:ff:ff:ff brd ff:ff:ff:ff:ff:ff inet 23.23.195.111/32 brd 23.255.255.255 scope global vif12.0 ------------------------ root@dom0:~# ip route 23.23.23.147 dev vif12.0 scope link src 23.23.195.111 23.23.95.220 dev vif11.0 scope link src 23.23.195.111 23.23.23.141 dev vif10.0 scope link src 23.23.195.111 23.23.195.0/24 dev eth0 proto kernel scope link src 23.23.195.111 default via 23.23.195.254 dev eth0 DomU (1st host debian01): root@debian01:/etc/powerdns# ip route 23.23.195.111 dev eth0 scope link default via 23.23.195.111 dev eth0 ----- root@debian01:/etc/powerdns# ip a l 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:16:3e:0f:26:8c brd ff:ff:ff:ff:ff:ff inet 23.23.23.141/32 brd 23.255.255.255 scope global eth0 DomU (2nd host - debian02 ): debian02:/etc/powerdns# ip route 23.23.195.111 dev eth0 scope link 23.0.0.0/8 dev eth0 proto kernel scope link src 23.23.95.220 default via 23.23.195.111 dev eth0 ----------- debian02:/etc/powerdns# ip a l 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:16:3e:57:e7:0f brd ff:ff:ff:ff:ff:ff inet 23.23.95.220/8 brd 23.255.255.255 scope global eth0 Am I missing something or those machines dont have a chance to see each other ? regards WZ -- Wojciech Ziniewicz http://rfc.sunsite.dk/rfc/rfc2324.html -- To UNSUBSCRIBE, email to debian-isp-REQUEST@... with a subject of "unsubscribe".
