Topic # 50135 23-Nov-2009 18:37

Have a home LAN with a couple of Win XP's and a linux mail server. Recently added a desktop which for some reason cannot have its IP address resolved by the server. All clients have static ip addresses(192.168.0.50-56) but the desktop has exactly same configurations as other clients but always has my EXTERNAL IP address resolved whenever logging on for mail.
postfix/smtpd[9433]: Anonymous TLS connection established from unknown[121.xx.xxx.xx]: TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)
Nov 23 17:53:21 mail postfix/smtpd[9433]: 0D70D62B: client=unknown[121.xx.xxx.xx], sasl_method=PLAIN, sasl_username=xxx

while other clients will have ip addresses resolved as per normal.

Using a Linksys wmp54G pci wireless card and router is a 3com 3CRWDR101A

My server firewall is fine and win xp has all the same settings

Anyone has an idea??

What is the output of "ipconfig /all" and "route print" from the desktop with problems?

All looks OK - nothing seems to be out of place there.

Are you still seeing the same problem where the external IP address is reported in the log files?

Yes unfortunately funny as it has same settings, apart from LAN ip as my laptop which resolves as should. The only difference is wireless cards. Stopped using linksys network manager and gone back to Windoze to see if that helps but so far not helping..
Let the fun begin....

Try adding the FQDN to ip address in the hosts file on the xp machine and see if that helps
