Outbound IP - 8.Feb.2004 8:30:00 PM

Hi all

I have five IPs bound to my external adapter: x.x.213.210 - 214.

ISA treats all outbound listeners the same. However, usually everything goes out on .210 but fairly often .212 is used. Those are the only two.

Any ideas on how I enabled .212 to be used?

Cheers

John

Hi John,

normally all outbound access should be sourced from the primary IP address assigned to the ISA external interface. However, I've seen some reports that now and then a secondary IP address is used. So, I assume this is some nasty bug.

As far as I know this is still an open issue although I was told that you could disable IP Routing in the IP packet filter properties to mitigate the problem. Note that disabling IP routing also disable the kernel data pump.

HTH,
Stefaan

Hi there!
Stefaan, i didn't know what is the "kernel data pump"?

I'm with the same problem described above.
It happens on ISA 2004 too?

Thanks in advance!

I have a question regarding the opposite of the above issue. Is there a way to force ordinary outbound web traffic, for example, out one of many bound IP addresses on the external interface other than the default machine IP? I have ISA 04 running for publishing and inbound VPN, but now that those services have been established, we are migrating off the older ISA's and I need to add outbound web access. I would rather not mix the services on one address since it will make life easier the next time I need to migrate. I would also rather not have to contact all external users and make them alter the way they contact the server. Forcing web traffic, or even SMTP outbound, on a particular IP would be my preference. Is there a slick way, or would I be better off changing the machine IP?

Any help is appreciated
