In jail ping: sendto: Can't assign requested address

Hi All,

In a jail, the raw socket is enabled in the config, and DNS is added in /etc/resolv.conf.
but it is unable to access internet and unable to ping,

Code:

root@cgr:~ # ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
ping: sendto: Can't assign requested address
ping: sendto: Can't assign requested address
ping: sendto: Can't assign requested address
^C
--- 8.8.8.8 ping statistics ---
3 packets transmitted, 0 packets received, 100.0% packet loss
root@cgr:~ # ping yahoo.com
ping: Unknown host

Jail network config:

Code:

export jail_cgr_ip="lo1|127.0.1.3,bce1|192.168.50.4"

Another jail, configured with IP 127.0.1.4 and 192.168.50.7 on lo1 and bce1 respectively, can ping and access internet. The netstat -nr output is similar:

Code:

Internet:
Destination        Gateway            Flags     Netif Expire
127.0.1.4          link#6             UH          lo1
192.168.50.7       link#2             UH          lo0

In pf.conf:

Code:

ext_if="bce0"
int_if="bce1"
jail_if="lo1"
jail_net=$jail_if:network
host=xxxxxx
nat on $ext_if from $jail_net to any -> {$host}

Help is appreciated.
