>Description:
A jail running with IP1 can sometimes see established connections between IP2 (used by an other jail) and a remote host, in it's netstat output.
In my case:
wendy.osilex.net is a jail that was assigned IP 87.98.200.163
ike.osilex.net is a jail that was assigned IP 87.98.200.164
[root at ike /]$ netstat -n
netstat: kvm not available: /dev/mem: No such file or directory
Active Internet connections
Proto Recv-Q Send-Q Local Address Foreign Address (state)
tcp4 0 0 87.98.200.163.25 85.237.44.155.4245 SYN_RCVD
