    I'm trying to write some iptables rules so that I can let someone
    telnet to machines on a 10.0.0.0 network but not allow them to telnet
    anywhere else.. effectively blocking outbound telnet to ANYTHING
    except the machines on the 10.0.0.0 network. I thought I had it but I
    guess I don't. The rules are as follows...

    # allow outgoing telnet traffic
    /usr/sbin/iptables -A FORWARD -p TCP -i eth2 -d 10.0.0.0/8 --dport 23 -j ACCEPT
    # block all other outgoing telnet traffic
    /usr/sbin/iptables -A FORWARD -p TCP -i eth2 -d 0/0 --dport 23 -j DROP

    This machine is a Compaq DL760 with 2 dual port 10/100 cards in it and
    eth2 is the first port on card 2.

    Any help would be appreciated.

    Thanks!

    -Ben
