Hello
Thank you for your reply
Yes the mail server is on the internal network not on DMZ, there is no other
publishing mail server this is the only one, there is web publishing rule
that use the same ip address as the mail server but this one will use port
80 not 25
And I forgot to say that the mail server it self is behind isa caching
server
Best regards
hanan

If your mail server is on the internal network and not on the DMZ, you don't
need packet filter. Second, ISA does not accept pings out of the box so don'
t worry about that. The inbound packet filter that listens on 25 might
conflict with the publishing rule also trying to listen on 25 (if you are
using the same ip) Take the packet filter out and restart the firewall
service.

Hello
I'm trying to publish internal mail server on isa server, I read the
instruction in Dr Shinder book and I read the article on isa.org but nothing
work
I create a secure mail wizard on server publishing with the internal ip
address of the mail server and the external ip address of the isa server
I create protocol rule to allow smtp port 25 outbound, I create ip packet
filter for smtp port 25 for inbound, local port fixed 25 and remote port all
I can telnet the external ip address with 25 as 1.1.1.1 25 from inside I
have answer, but when I try to telnet from outside I can't no answer
As Dr Shinder said in his book you should be sure that your external ip
address is listening to the port 25, I did netsat -na to see the external
ip address with the port 25 I didn't find it , I didn't find the port 25
with my external ip address and I think here is the problem but I don't know
what I must do?
I can ping the external ip address from inside but I can't ping it from
outside
Could you please help
Best regards
hanan
