ISA doesn't "depend on" RRAS for local net routing, but it does know how to 
gather data from it.

Of course- that's its purpose...

2 caveats, though.  One, if RRAS is installed on the box before you install 
ISA, and you have a static route to other networks in RRAS, ISA won't take that 
network and automatically add it to its list of IP's for the internal network.  
It will, however, take a system route added with "route add" and add the 
destination network to it's Internal list.  My guess is that you wrote it like 
that on purpose as the stack is more authoritative for "local" 
traffic.

Two, while I agree that in normal RRAS situations you should use the RRAS 
interface to manage your routing, when it comes to RRAS on ISA, ISA should
*not* have to depend upon the RRAS service for it's own routing needs. 
Remote Access might go down, but internal routing to other subnets will 
continue to work properly if the routes are added directly to the system rather 
than RRAS.

I misspoke..

RRAS can carry routes that do not appear in the system routing table.
ISA doesn't care where the routes are; it "merges" them.

RRAS doesn't write to the system routes - just its "own" routes.  If I 
create a static route with "route -p add" RRAS will see it and use it, but 
RRAS cannot delete it.

When it comes to ISA routes (for ISA itself, as in a complex network), I
*always* use system routes and not RRAS.  I assume this is one of the 
excpetions you note, yes?

Actually it reads and writes.
As a rule of thumb; you want to populate your routes using RRAS if its
installed.
There are exceptions to this, but they're few and far between...

Doesn't RRAS read the Windows table? Not that it matters because there's no
RRAS on the server I as working on.

I was under the impression that it was actually up up down down left right
left right a b start. (And ooga booga.)

Just remember that if you have RRAS installed you get *two* routing tables.
The RRAS db and the one you get from cmd.exe (route print).

I don't know if this helps, but I just helped someone yesterday by saying
that.

Na, it's send quick email to ISA list, clear and recheck event log for the
absence of annoyance, (say ooga, booga if you want to), check email, done.
