Gateway problem?

[incoma]

Hi there...

I have an Linux box (RedHat 6.0) configured as Mail server, Web Server and Gateway.

My users (with Windows) access to the Internet using this as gateway, no problem!

My problem is when i want to use FTP client in windows my Gateway doesn´t resolve the Names.

Any help would be greatful.

Most likely your resolver is not configured correctly, for more information:

man resolver

then add the IP address of your DNS servers to /etc/resolv.conf

Good Luck!

Click the NHF button and do a bit of reading..

Make sure you have ip_masq_ftp loaded.. if not read that above link.

I think the resolv.conf it´s ok....

search myDomain.com
nameserver 127.0.0.1
nameserver IP of dns.myISP.com
nameserver IP of dns.myISP.com

i tried to make nslookup and make some queries and seems ok too....

$>nslookup

Default Server: localhost
Address: 127.0.0.1

> www.linuxnewbies.org (http://www.linuxnewbies.org)
Server: localhost
Address: 127.0.0.1

Name: www.linuxnewbie.org (http://www.linuxnewbie.org)
Address: 63.236.73.208

Maybe ip_masq_ftp modules not loaded..
Will try! thanks

Ok my windows users can now use FTP clients!!

There has 2 problems...

1st
I have to put this lines into the rc.local
# 1) Flush the rule tables.
/sbin/ipchains -F input
/sbin/ipchains -F forward
/sbin/ipchains -F output
# 2) Deny all forwarding packets except those from local network.
# Masquerage those.
/sbin/ipchains -P forward DENY
/sbin/ipchains -A forward -s 192.168.0.0/24 -j MASQ
# 3) Load forwarding modules for special services.
/sbin/modprobe ip_masq_ftp
