Hi David,

but if you say "it should be send only", how get the replies back? Really, I
don't understand it :-(

Regards,
Stefaan

Hmm...my mistake again. It`s been a while, since I have seen a ISA
server and I have no access to one right now.
However, if the options you mention are the correct ones for UDP, I
would say that it should be send only - not send/receive.

I think I`d better build med e new ISA server, before I forget where I
put
The CD :-)

Hi David,

sorry, but in my ISA (SP1 v122.166) for UDP protocol directions you can
NOT select direction outbound. The only choices are: send/receive
(equivalent of TCP outbound), receive/send (equivalent of TCP inbound),
send and receive. Could you clarify your definition of outbound.

STefaan

I should clarify my mixup of the terminology:

The needed protocol definitions:

UDP 500 outbound
UDP 10000 outbound

I tried the send receive mode first, but never got it to work.
Can`t explain why.
Some suitable protocol rule has to allow the definitions.
It only works with securenat clients. Firewall clients has to be
Disabled temporarily.

Hi David,

can you post the protocol definitions and rules you have to create?
I think UDP 500 send receive and UDP 10000 send receive is all you need.
Correct?

Stefaan

Provided that you are using the 3000 series client, it will
Provide the option of UDP encapsulation. It is up to you to enable
It. You do not have to create packet filters, but you do have to
Define the described protocol rules and disable the firewall client.
I don`t know why, though I`m sure some tweaking of the clients .ini
File could fix this

I think If install the Cisco clients vpn software on the machine, then
will it provide the udp encapsulation for me or do i have to apply
filters
to the isa server to allow this to go through?
