Isa 2004 & SMTP filter: how to turn off NDR's



  • 1. ISA 2004 DHCP Limit?
    Even though I've enabled the VPN connection for 50 clients (using the 120 day trial ISA2004 download), I can only see 10 DHCP address leases in the DHCP configuration. Is the 10 user limit part of the 120 day trial, or am I doing something wrong on my ISA configuration? Thanks, Rob
  • 2. URL Set
    I have created a URL set just a test to see if it could stop access to a certain web site, but I cannot see where I can apply this rule. I guess it's from the FIREWALL POLICY, then right click; then New, and ACCESS RULE, but I cant see where to go from here job to stop this, or am I barking up the. wrong tree altogether Thank you very much for your help Debbie

Isa 2004 & SMTP filter: how to turn off NDR's

Postby Paul De Bie » Tue, 19 Jul 2005 22:16:15 GMT

Hi all,

does anyone know how I can prevent the SMTP Virtual server to send out 
NDR's for incoming messages with a destination that does not exist in 
our domain?   Most of these messages are spams.  The NDR's hang around 
in the queue for days because the senders' (spammers) address doesn't 
exist either.
Also we are having a mail gateway (X-Wall) further along the line which 
handles the NDR's for us, so I really don't need the ISA server SMTO 
filter doing the same.

(NB: IN Exchange, SMTP Virtual server, I believe you have this option to 
turn off NDR. However, I don't find in the ISA SMTP Virtual server...)

1.ISA 2004: Turn off web proxy filter for VPN connections

I use ISA 2004 as router and VPN gateway. When http traffic traverses 
through the isa computer it will be redirected to it's cache and the request 
to the web server seems to come from the isa instead of the client on the 
other side of the router.
This is not very helpful when using the client's ip as one of the security 
factors, so I disabled the Web proxy filter on the pre-defined HTTP protocol 
and now the paket gets routed and seems to come from the client.
When it comes to VPN connections (both client-to-site and site-to-site) this 
method doesn't seem to work and HTTP traffic is still redirected to the 
cache although Web proxy filter is disabled. Is there a way to turn of that 
behaviour for VPN connections as well ?

Thanks, Robert
