Hi everyone,

I am running slackware 3.6(ipfwadm) and 7.0(ipchains) on different systems
sl3.6 - 192.168.0.4, diald 0.16.5, ipfwadm, kernel v2.0.35
sl7.0 - 192.168.0.6, diald 0.99.2, ipchains, kernel v.2.2.13

I need some advice.
I need to do the following to the clients' PC:
1) only allow clients to send/receive to/from local mail server
2) do not allow www browsing for certain clients.

Will these statements do it?
ipfwadm
*******
/sbin/ipfwadm -F -p deny
#Turn on the forwarding from 192.168.0.X
/sbin/ipfwadm  -F -a m -S 192.168.0.0/24 -D 0.0.0.0/0
# Allow email to go to the mail server (for everyone)
/sbin/ipfwadm -F -a accept -b -P tcp -S 0.0.0.0/0 1024:65535 -D 192.168.0.4 25
# Reject Web connections to outside Web Server (from 192.168.0.250)
/sbin/ipfwadm -F -a reject -b -P tcp -S 192.168.0.250 -D 0.0.0.0/0 80 
1024:65535

ipchains
*********
/sbin/ipchains -P forward DENY
- Allow ip forwarding for your IP MASQ machines 192.168.0.0
/sbin/ipchains -A forward -s 192.168.0.0/24 -j MASQ
# Allow email to go to the mail server (for everyone)
/sbin/ipchains -A output -s 192.168.0.0/24 -d 192.168.0.6 25 -j ACCEPT
# Reject Web connections to outside Web Server (from 192.168.0.250)
/sbin/ipchains -A output -s 192.168.0.250 -d 0.0.0.0/0 80 -p tcp -j REJECT

I would appreciate all the help I can get.
Better still, if someone has any sample rules for the above or similar rules,
please write to me at [EMAIL PROTECTED]

Thanks in advance.
