ISA between VLAN's
Posted on 2008-10-13
I have a weird problem with a certain software (Bloomberg), Bloomberg needs internet connection to pass through, certain ports has to be opened, all of that seems normal, when i try to connect through ISA it never connects and it keeps looking hopelessly for connection.... I have 2 Vlans as follows:
192.168.1.x (lets call it Vlan 1)
192.168.2.x (lets call it Vlan 2)
Isa has 3 NIC's, one connected to Vlan 1, second connected to Vlan 2, Third NIC is for Intra-Array communication...
The Cisco Firewall (my gateway) and all servers (DC's, application servers, exchange, etc..) are connected to Vlan 1
all users are connected to Vlan 2
ISA has an access rule that allows network traffic from internal to External for that user am logging in with, i can access internet freely with no restrictions at all, except this software.....the software requirements is that i should be able to reach some servers like pdir.bloomberg.net, i can't even ping those addresses from Vlan 2 and actually i cannot ping any other name or IP in internet, can resolve names though, i used firewall client and it didn't work too...
Where does the problem occur ?
Why when i tried this software on a pc on VLAN 1 it connected without problems at all ( i had the cisco's IP as my gateway and didnt go through ISA server) ?
Is it ISA or routing between VLAN's?
Shouldn't the ISA pass the traffic from VLAN 2 to VlAN 1 where my gateway is ?
Please assist me with that critical problem since business is depending on that Bloomberg software.
