Firewall problems on my ubuntu gw
Hi,

I make an ubuntu based gateway with dns, dhcp, proxy and a firewall.
The problem is with the firewall, a classroom is connected to gw.eth1 with private ip
17.18.43.XX and gw.eth0 with public ip 134.201.34.XX is connected to internet trought 134.201.3.1 and others server like LDAP on 134.201.34.55 ect...


classroom.private172.18.43.101-143--------172.18.43.100[eth0] GW |dhcp|dns|ntp|proxy|firewall [eth1]134.201.34.55-----{LDAP/SMB}--{Cups}----{134.201.3.1GW}...(INTERNET)

My GW is on ubuntu server 11.04
I use firehol as firewall but LDAP can't connect to classroom trought GW and viceversa.

I'm new to linux and i don't find how i configure firehol, access to dns is needed by LDAP and others servers, classroom need LDAP,DNS,SMB,DHCP,TFTP for PXE,SSH, internet trought proxy.

thanks.



thanks
