Re: two NIC's in a jail

Thanks for replay.

netstat -an | egrep 'tcp4.*80 .*LISTEN'
say:
netstat: kvm not available: /dev/mem No such file or directory <- is
inside a jail.
tcp4    0        0 *.80        *.*        LISTEN

grep -i Listen /usr/local/etc/apache24/httpd.conf

Listen 80
Listen 443

From the internal IP is no Problem.
You are right. I'm not sure on wich IP's Apache is listening.

I have change the Listen directive to the external IP in httpd.conf
Listen 213.70.80.92:80

netstat -an | egrep 'tcp4.*80 .*LISTEN'
now say:
tcp4    0        0  213.70.80.92:80        *.*        LISTEN

But apache is not availble from Internet.
From Intranet... no Problem.

When i use tcpdump on Host i can see Traffic.

Whats wrong?
