Which dictionary is “fecious” listed in?  Everything that I see wants to 
correct the spelling to facetious.

It is, too…

 

“Fecious”; adj. insultingly tongue-in-cheek.  “A smartass with a shitty

Well, since “fecious” isn’t a word, I can only imagine the closest thing 
to it... Which, as it happens, does come out of a kitty ;)

“I was just being facetious” – I see; too much playing with the kitties

“SMTP NAT and source IP packet filtering so that I can specify the two 
Internet subnets that are permitted through.” – this is only possible using 
Server Publishing; as I stated, packet filters are only useful for ISA-local 
services.  Server Publishing rules allow exceptions that you can use to block 
unwanted source IPs.
 
“need to deny anonymous SMTP connections” – that’s a completely 
different-colored barrel of horsemonkeys. I think you mean “unknown”?  ISA 
cannot authenticate SMTP connectio0ns at all.

Nope; that's not true, either.


I was just being facetious. I have been inspired by:

SMTP Server Publishing gives you the SMTP  Filter and (with ISA 2000 & 2004), 
the Message Screecher.]


For this requirement I just need an SMTP NAT and source IP packet filtering so 
that I can specify the two Internet subnets that are permitted through. 


This is far more capable than the "zealot technique".

It's packet filters that are for the "openaport" fuuls and they only apply to 
services operating on the ISA itself.



Is this an SBS deployment?


Not in the Microsoft SBS software sense, but maybe in employee count. There is 
a dedicated ISA server and dedicated Exchange server. The change is that email 
protection has been outsourced to Postini and I need to deny anonymous SMTP 
connections from the rest of the Internet.

Actually Mr. Teacher, can I have that back. I want to say, at the end of the 
day, it is the packet filters. :) Server Publishing rules in ISA 2000 are just 
for all of the "hardware firewall" zealots.

However, in appears as though I can only specify one source subnet per packet 
filter.

Been awhile since I used ISA 2000... what is the best way to restrict SMTP 
connections from several specific Internet IP subnets?

Thanks.
