FYI....
Figured this out by configuring IP Filters for the different subnets. There are 3 steps to this process.
From Nortel Device Manager Gui:
(First Step)
(Creating Filter)
* Go to IP Routing.
•Filter
•Filter Tab
•Insert a filter
•Type: Click on Destination radio button (Nortel notes: Technically , you can do a source as well, they are about the same if setup properly).
•Now, assuming you want all http traffic, you set the DstAddr to 0.0.0.0 (The default) and the DstMask to the same.
•SrcAddr and SrcMask you can specify if you want only 10.0.0/8 traffic filtered, or leave it if you want.
•ID and Name you can set as you want.
•The important part comes under ProtocolType where you choose TCP then DstPort is set to 80 (The default for http traffic). Of course you might want to create more filters for ftp, https and http-alt (port 8080) traffic.
•The DstOption would be equal (when traffic equals TCP port 80 do)
•Mode is set to ForwardToNextHop and EnableStatistic if you want to see how many times this filter is used.
•NextHopForwardIpAddr is the IP Address of the proxy server.
•Insert to save this filter
(Second Step)
(Filter Set)
* Now this needs to be added to a filter set.
•IP Routing
•Filter
•Source/Destination Sets Tab: [Insert] a set id and Name
•FilerIdList: This is where you select the filter(s) to implement. Select the one(s) you created and insert it.
Third Set
(Assigning The Filter to A Port)
* Now you need to assign the filter to a port.
•IP Routing
•Filter
•Filtered Ports Tab: [Insert] a list of ports.
•Ports: Select the port or ports you want to have routed through the proxy server.
•FilterSet: Choose the filter set you want assigned to the port.
•DefaultAction: What you want the passport to do to all traffic that is not filtered. Select forward to have all other traffic handled as usual.
•Enable the filter and test it
