I just gave this a try and it ended up causing all sorts of problems with my Static Address Mappings and Inbound Tunnels. Here are my IP block assignments:
68.217.104.24/30 (255.255.255.252) 68.217.104.16/29 (255.255.255.248) 68.217.104.64/27 (255.255.255.224) When I set an alias for 68.217.104.16 - 255.255.255.248, I get a warning message saying "IP Address is Network Address". Then my Inbound Tunnels give me a warning messages like "Tunnel 5, starting (68.217.104.17) doesn't match any interface or alias". And in my Static Address Mappings I get warning messages like "Map 1, (68.217.104.20) is not mapped to a valid IP address or alias". What am I doing wrong? -Brian -----Original Message----- From: Brian (Mushkin) [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 24, 2004 12:27 PM To: 'david raistrick' Cc: [EMAIL PROTECTED] Subject: RE: [gb-users] multiple external subnets on a single interface I'm embarassed that that never occurred to me :-) Thanks! -----Original Message----- From: david raistrick [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 24, 2004 12:07 PM To: Brian (Mushkin) Cc: [EMAIL PROTECTED] Subject: RE: [gb-users] multiple external subnets on a single interface On Tue, 24 Feb 2004, Brian (Mushkin) wrote: > I have the same setup from my ISP. It works fine although under 'NAT > -> Aliases', GNATBox tells me "...IP Address is on unique network". > No You should add the netmask for the first entry in an otherwise undefined network. For example, I have 4 aliases: 10.50.1.5 10.50.1.6 10.60.1.7 10.60.1.8 My physical interface has 10.50.1.4/24 assigned, so there is no need to assign a netmask for the two 10.50.1.0/24 addresses. (the gnatbox automaticly adds a /32 netmask, or 255.255.255.255) 10.60.1.0/24 is not defined elsewhere, though, and the NAT>Aliases entry is the first definition for the network. I should define a netmask in the entry, then, using: 10.61.1.7/24 10.60.1.8 will not need a netmask. Done this way, the warning you mention will go away, and local-network routing will be handled properly. ...david -- David Raistrick Systems Administrator - Global Technology Associates, Inc [EMAIL PROTECTED] Disclaimer: All opinions expressed are the opinions of David Raistrick, not necessarily those of GTA, Inc. ------------------------------------------------------ To unsubscribe: [EMAIL PROTECTED] For additional commands: [EMAIL PROTECTED] Archive: http://archives.gnatbox.com/gb-users/ ------------------------------------------------------ To unsubscribe: [EMAIL PROTECTED] For additional commands: [EMAIL PROTECTED] Archive: http://archives.gnatbox.com/gb-users/
