RE: Unable to access IP

Hello,

Thank you for posting here.

According to your description, I understand that:

You cannot access the security server from internal network while accessing
it from external network is OK.

If I have misunderstood the problem, please don't hesitate to let me know.

To have a clean understanding of your issue, could you please answer the
following questions?

1. What are those 5 static IP address? Are they public Ipv4 addresses or
static assigned private addresses?
2. How many internal networks do you have behind the ISA server?
3. Do you mix different logical IPv4 networks in one physical network
(broadcast domain)?
4. Does your network topology look like:


Internet
|
|
SBS 2003 with ISA server
|
|
|--------Internal clients with private addresses
|
|
2 server with public addresses

If you have any questions or concerns, please do not hesitate to let me
know.






Best regards,

Hi,

Thanks for the update.

I'd like to know your network topology to help to check whether there is
incorrect configuration in the ISA that will block the traffic. A IP
address schema will be useful to narrow down the issue if the ISA server
does block the traffic.

1. As you mentioned that the security server has the static public address
assigned, I'd like to know where the security server is connected to. Do it
connected to the internal network?
2. Could you please explain which IP network(s) is in the internal network?
Is it the network that contains 5 static public address? Is it a public
IPv4 network instead of the private one?
3. What network are other clients computers without the static public
address in?

If you have any questions or concerns, please do not hesitate to let me
know.
