what i have is that i can access the private ips of the LAT ( internal ) hosts 
behind the ISA because I have a tunnel configured between 2 routers

so i will not need to access the internal host using the isa public ip and 
publishing rules.
for ex  i need to access pcanywhere for ex on an internal host from one site of 
the tunnel using the host private address what shall i do to allow pcanywhere?

Regards,

Walaa

  Ordinarily, to allow access to internal hosts you would use a server 
publishing rule to that host. However ISA 2000 can only do this for tcp and udp 
traffic, so what you are trying to achieve will not work.

  Hi

  I have ISA 2000 installed on windows 2000 server; 

  What shall be done to allow access to the internal hosts ?? 

  Packet filters can be used to allow access to the ISA itself and the 
perimeter hosts ...what about the internal hosts defined in the LAT table??

  For ex: i want the internal hosts to be able to ping remote sites ; so i need 
to allow icmp response ( in ) to my internal network so how to specify it ??
  There is a predined packet filter that allows icmp response ( in ) to the ISA 
itself so ISA can ping remote sites.



  Any help is appreciated.



  Regads,

  Walaa
