I installed a TMG, I created a rule that allows all outgoing traffic.

but the DC does not ping the Wan TMG leg.
The DC ping  the leg LAN.

I used the wizard and it seems that networks and routes are correct.

>> allows all outgoing traffic.
how do you create the rule ? is it for all user and protocols from internal to external and local host ?

open TMG monitor and see which rule denies the traffic.

BTW: it is not a good config to have such rule. only needed protocols should be allowed on the firewall.

thats not related to ping.


while pinging the external tmg IP address, monitor the traffic.

always there are a lot of red (deny) connection in ISA monitor. you can filter the log to show only traffic from DC based on client ip address.

Can you post a screenshot of your current access rules ?

why do you want to be able to ping the external interface of TMG ?

todas las redes --> all the networks
todos los usuarios --> all the users
todo el trafico saliente --> all the outgoing trafic
