All destinations for your network will be aliases on the outside network of your Firewall, which your Cisco's internal NIC is connected to, so no route required on Cisco. So if the network that your Cisco and Gnat are connected to (via your hub) is 199.199.199.0/24 for instance, then the destination address for anything destined for your network will be an address within the 199.199.199.0 network, which your Gnat then does an Inbound Tunnel to the address of host within your private network.
Nobody should be talking to your Internal networks (ie what's behind your firewall) directly Hope that clarifies :) -----Original Message----- From: David Kraut [mailto:[EMAIL PROTECTED]] Sent: 22 November 2002 14:55 To: '[EMAIL PROTECTED]' Subject: [gb-users] Routing Question... I have a Gnat box Pro 3.3 setup and I'm trying to better understand what is going on under the hood with routing... Here's the basic config. T1 from ISP goes to Cisco router external interface, Cisco internal Ethernet goes to mini hub, Gnat box pro external NIC is also connected to same mini hub. The Gnat box default gateway is the Cisco internal Ethernet so I understand how packets find their way from the Gnat to the Cisco but how does an external request find it's way from the Cisco internal NIC to the Gnat external NIC? Do I have to setup a gateway on the internal Cisco Ethernet or will the Cisco simply forward all packets to the subnet (mini hub) which includes the Gnat box external NIC? I'm so confused! :-) --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] To subscribe to the digest version first unsubscribe, then e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Archive of the last 1000 messages: http://www.mail-archive.com/[email protected] This e-mail and its attachments are intended for the above named recipient(s) only and may be confidential, legally privileged and protected by law.
