Routing Network traffic through ISA server

Hello all,

I have been asked to route all internet traffic through our ISA server. Am I able to do this by changing the default route on the core switches?

I am not sure if this is possible can anyone help?

Thanks

Andy

Re: Routing Network traffic through ISA server

yes it is true

default route must to isa server

such as

ip route 0.0.0.0 0.0.0.0 192.168.1.240(isa server ip address)

and you must write static route isa server to switch

192.168.0.0 255.255.0.0 192.168.1.200(switch vlan ip address)

OK can I just make sure I understand this correctly!

Create a default route to the ISA server on the core switches

ip route 0.0.0.0 0.0.0.0 10.0.2.23(isa server ip address)

This part is not that clear to me

Create static routes from the isa server to the vlan ip addresses on the core switches

ip route 10.0.2.23 255.255.255.255 10.0.32.3 (VLAN 1)
ip route 10.0.2.23 255.255.255.255 10.0.33.3 (VLAN 2)
ip route 10.0.2.23 255.255.255.255 10.0.34.3 (VLAN 3)

etc...

Many thanks

Andy
