Danny, Is the target server seeing the raw address of the client connector or the gateway address of the Gnatbox? If it is the Gateway you could try this fairly simple test? On the target server just add an entry in it's host file (if it uses DNS & hosts) to resolve to gateway like
192.168.x.254 gateway Or something like that......it may help out, and once you know one way or the other you can determine how to deal with it permanently. -- Best Regards, Steve Leach Network Manager MI International Ltd Tel: +44 (0)1642 356 205 Fax: +44 (0)1642 356 229 [EMAIL PROTECTED] www.mi-int.com www.askalix.com DISCLAIMER Any opinions expressed in this e-mail are those of the individual and not necessarily of MI International Ltd.
