Can't send email attachment behind linux router and D-Link router
I have a linux router with 2NIC plus with iptables firewall and snort....eth0 is connected to my ADSL modem...and eth1 connected to my DI-714P+ router at WAN port by using cross cable. DI-714P+ is D-Link wireless router.
1-My problem is...my wireless client cannot send email with attachment...
2-I try to connect directly from eth1 to a single pc ( XP ), and try to send email with attachment using Outlook Express...it succesfull..
3-When I try to connect the ADSL modem to D-Link router dirextly and try to send email attachment from wireless client...it succesfull...
3-I think my firewall is ok because i already open port for outgoing email in the firewall setting like below:
OPEN_TCP="20 21 110 143"
OPEN_UDP="20 21 110 143"
I use arno-iptables-firewall-1.8
Thank you.

does this only happen if the firewall (iptables) is active? then the missing port 25 might be the problem
ASKER
yeah...happen when iptables firewall is active...the port 25 you mean i need to allow tcp and udp for port 25?...i try
tcp port 25 should be sufficient

now my client can send email attachment after i do this:
linux router -(connect from eth0 to vpn router WAN port)- > d-link vpn router -(connect from Lan at vpn router to WAN port)-> dlink wireless router -> wireless client
but when i use this, my client cannot send email with attchment...
linux router - >d-link wireless router -> wireless client
i try to reset the wireless router and just use the basic configuration...the problem is still the same...
what do you think?
