So I guess the best thing to do is, as quick as possible, move over to a 192.168 address range -----Original Message----- From: Michel Erdmann [mailto:[EMAIL PROTECTED] Sent: 04 March 2003 16:25 To: Exchange Discussions Subject: RE: Internet mail taking an obscure extra step? 192.192.192.0 isn't a private range RFC1918 states: The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets: 10.0.0.0 - 10.255.255.255 (10/8 prefix) 172.16.0.0 - 172.31.255.255 (172.16/12 prefix) 192.168.0.0 - 192.168.255.255 (192.168/16 prefix) I'm wondering why the remote servers doesn't block your mail, because basically you are using them to relay. Must be because the remote mail server sees your mail server as 'local'.... (some quick relay testing for the tajen.edu.tw domain show correctly configured relay restrictions) Michel > -----Original Message----- > From: Niki Blowfield - Exchange [mailto:[EMAIL PROTECTED] > Sent: Tuesday, March 04, 2003 5:07 PM > To: Exchange Discussions > Subject: RE: Internet mail taking an obscure extra step? > > > I think I'm on to something > > The network here is a privately addressed LAN, > mailgate.partition.co.uk resolves to the firewall, which forwards port > 25 to the exchange server > > The LAN network address is 192.192.192.0/255.255.255.0 set up before I > arrived, I was a good engineer and gave the other subnets 192.168.x.x > ranges > :) > > 192.192.192.0 isnt a private range is it? > > When I put one of our server addresses into an IPWHOIS search, this > tajen.edu.tw domain comes up as the owner > > I guess I need to change the network address range here?
