Hi all

This is my first post here, so I hope this gets in the right way :)

We have a 100mbit Internet Connection that we are building (this is a new 
line). We are setting in new eq. and we plan to move over 1 and 1 service.
We have a Fortigate 500A Firewall in front here, but we need to setup a router 
or switch or some other nice box in front of the firewall.
The reason for this is that we have a /21 net routed to this fw, but our 
supplier runs their eq. on 10.x.x.x IP's and they will not let their eq. be 
exposed by real ip's. So the issue for us comes when the FG500A is to 
communicate with the world, it sees that the default gw is on a 10.x.x.x. net 
and therefore uses it's own 10.x.x.x. assigned IP address for transmitting 
this. This naturally gets dropped by the isp.

Solution is to set a Cisco switch / router in front with 2 IF's. One with our 
legal IP and one with the 10.x address. This way this unit will become the 
default gw for our fg500a and will transmit with it's real ip address.

But that leaves the question as to which unit to use in front.

We have a couple of 2801 in stock, but they can't handle the traffic. We need 
something that can withstand an attack and at the same time deliver enough 
performance for the 100mb link.

All suggestions are welcomed , also if anyone has a similar setup and therefore 
has any hans on experience with such a front end that would also be great.

Thanks
