HELP

[Mike Forster]

I am in real need of help here
I need to configure a Linux box for use as a NAT firewall

I am using Turbolinux Server 6.0 Lite

I have configured the ipchains as follows

ipchains -P forward DENY
ipchains -A forward -i eth1 -s 10.6.2.0/24 -j MASQ
ipchains -A input -j REDIRECT 25 -i eth0 -p tcp -s 0.0.0.0/0 -d 10.6.2.4/32
25

When they are set up I am unable to telnet into the box from within the
system

The plan,

(not completely configured yet but someone may be able to help me get the
files right)

Internal network 10.6.2.x - eth1
External 212.19.??.?? (waiting for the link and ip) - eth0

Nothing incoming except HTTP pop and SMTP
HTTP - apache running on the firewall itself
Pop and SMTP on 10.6.2.4 - Exchange Server

Outgoing NAT / MASQ transparent proxy

Internal Access to telnet Samba and other std unix services.
