The room containing our internet router and ISA server is to have the server removed to another location, leaving only the router in place. Can someone advise me on what I propose to do below is advisable or whether it is a really bad idea.
Out current setup is a network with 8 VLANs. Internal routing is performed by a 3550. The connection to the internet is thus:
Cisco 3550 -->(trunk)--> Cisco 2960 --> ISA 2004 --> Cisco 1841
Because the ISA must be moved to the same physical location as the 3550 (which is no where near the internet router), what I want to do is:
ISA 2004(default gateway) <--> Cisco 3550 --> (trunk) --> Cisco 2960 -->(internet VLAN) --> Cisco 1841
I'm a bit concerned about the security issues regarding the 'internet VLAN' I would have to create for the connection between the ISA's outbound interface and the 3550, and the connection between the 2960 and 1841 router.
