Title: Email Server behind Natting not working Post by: kartikpatel on Sunday 17 February 2013, 12:58:34 am Hi, & anybody can help me.
I am using Endian Community firewall V 2.5.1. One of the task is failing as described below EFW Configuration: RED, Orange and Green Red--- Multiple IPs from ISP. x.x.x.208/28. Configured x.x.x.210/28 on RED interface Orange--- DMZ servers with subnet 192.168.0.0/24. Configured 192.168.0.1 as Orange gateway Green-- LAN with subnet 192.168.1.0/24. COnfigured 192.168.1.1 as green gateway Email server IP x.x.x.222 which is not configured on server. Rather 192.168.0.13 is configured on the server I used DNAT for configuring x.x.x.222 to 192.168.0.13 for natting. I am able to send out emails. I am able to ping to the IP x.x.x.222 I am able to telnet to IMAP, SMTP, POP3 ports from outside The problem is when someone send email to my mail server, my mail server accepts the email but fails to deliver to mailboxes. It gives x.x.x.222 connection timeout The same senario is working on Linksys with one to one nat enabled. Note: from my email server, i am able to ping to any other IPs except for any IPs on RED interface. All help is highly appreciated as i need to replace linksys with endian in production Thanks, Kartik Title: Re: Email Server behind Natting not working Post by: kartikpatel on Thursday 28 February 2013, 08:37:33 pm Bad to see no replies.
