Don't use RRAS to route out internet let ISA do it.
PS. Dial-up access with ISA (are using a modem or ISDN adapter?) works best
when your ISP is nice enough to allocate you a static IP address for your
dialup account (Demon Internet)
I have sucessfully implemented the following scenario:
1 ISA server with 56K modem attached.
create a normal Dialup entry in Network & Dialup connections.
Configure ISA to use it.
ISA is probably looking to bind to the dialup entry that you have deleted. you
should recreate it with the same name and then start the services.
After this modify the Routing Rule in the Network Configuration section to
allow automatic dialout.
To get exchange to initiate the dialout set up a protocol rule and filter to
allow SMTP traffic out, that should initiate the dialup connection when it gets
ip traffic destined for the external network.
Also create and allow rule for SMTP traffic in to your Exchange server. If
exchange is on the same machine then leave the SMTP Vitual Server ip address to
"All Unallocated" this way when you are connected to the internet, Exchange can
receive email on port 25 at the dialup interface.
Since you cannot bind it to an ip address permenantly because of the nature of
dialup networking.!
Hope this give you some pointers. good luck :)

Hi all,
I have a problem with ISA server and its refusal to let go of a dial up
When it was initially installed it was simply a web proxy so it was
configured to use a dial up connection. Since we have added an SMTP
server (exchange) to the box we now need to use RRAS and a default route
to get the mail delivered. Unfortunately the 2 connections (ISA Dial up
and RRAS static route) seem to conflict with one another (even though
the are essentially the same connection) so I decided to remove the dial
up connection from ISA and just have it initiate the default route
connection as well.
I have removed the dial up selection from both the default route and the
routing config in ISA but it wont let me delete the dial up connection
since it says it is still active. However whenever I restart the
services both the proxy and firewall service say the cannot bind to the
dial up interface.
Any ideas on how to fix this?
Thanks
Ash
