But if i put all sites on this ip, they work only in lan. If i use another ip they work external... I changed this ip to another vm, and doens reach external. If i check with : http://www.yougetsignal.com/tools/open-ports/ (delete name if u consider is reclam,pls) all ports on this ip are off. The ip works only in lan.

Hi,
look with tcpdump to find the issue, like

tcpdump -i vmbr0 host new.ip.of.ct

Shows nothing, after 5 minutes i do ctrl+C and write this :

0 packets captured
3 packets received by filter
0 packets dropped by kernel


After 10 minutes :


19:38:30.232136 ARP, Request who-has the-new-ip tell myip, length 46
19:38:30.287916 ARP, Reply the new ip is-at 00:26:18:d9:5d:84 (oui Unknown), le ngth 28


And on CT : tcpdump: ioctl: No such device

Hi,
do you ping in this time from outside to the CT?
If yes, then your ISP don't send the content??

Because tcpdump inside the VM - which interface name do you use and which network-modell (bridging?)
