Hello to you,
If I want to allow users to use some of port numbers ( services ), eg :
port 80 ( http ), port 53 ( DNS ), etc... only!
So, how can I set the ipchains and iptable to filt which port numbers (
services ) allow users to connect ?
Are there any samples about ipchains and iptables

iptables-save. It's equivalent only if
these are all your rules. "iptables-save" is a command that prints
your entire set of rules.
Your listing above shows 11 superfluous rules, because the default
policy in the INPUT chain is ACCEPT. That means, by default, the
INPUT chain accepts ever
-j ACCEPT
iptables -A INPUT -i eth0 -p udp --dport 53 -j ACCEPT
iptables -A INPUT -i eth0 -p tcp --dport 110 -j ACCEPT
iptables -A INPUT -i eth0 -p tcp --dport 443 -j ACCEPT
iptables -A INPUT -i eth0 -p tcp --dport 113 -j ACCEPT
So, any problem of the setting about ipchains and iptables ?
Very than

Dear All,
After the following setting of ipchains on 6.2 machine :
/sbin/ipchains -F
/sbin/ipchains -A input -i eth0 -p tcp --dport 20 -j ACCEPT
After the following setting of iptables on 7.2 machine :
iptables -F
iptables -A INPUT -i eth0 -p tcp --dport 20 -j ACCEPT
But I can connect to http:

Well, In my original message about this, I pasted an output of an error
I got when I would run iptables. It has something to do with modules.
Also, the reason I was going to try iptables is when I try to MASQ with
ipchains, there seems to be a "Buffer" that fills up after a day or so
that causes

I'm not sure what error you're getting but if you have ipchains on and
iptables on at the same time, and try to run iptables, it's being
interrupted by ipchains. T
Is that why I'm getting that error when I try to run iptables?
Thanks

No. If you attempt to run both at the same time ipchains takes
precedence on Redhat.

Like, for instance, use ipchains for packet filtering and iptables for MASQ?
Also, then I type iptables -L at the command promtp (Or iptables ) I get
this error:

Anyone know how to allow ports 137, 138, and 139 go
through in the ipchains and iptables commands?
