Network in Internal Network - 4.Sep.2006 7:50:54 AM

Hi Guys.

I have an ISA 2004 firewall.

I need a network in a network. As in subnetted VLANS behind a Cisco SW ( 3750 ) on the internal Network.

I've made a persistent route in ISA routing table. I made a new network in ISA with route relationsship. ( Can we agree that route relationsship is bidirectional? )

I've in the persistent route added a gateway, being the "outbound" interface on the Cisco SW, and on the "Internal" interface of the Cisco are the VLANs located.

I need serveral clients on different VLANS behind the Cicso thing, to have internet access. The are all Firewall Clients and Web Proxy Clients.

The are currently unable to access the internet..

I have an all outbound rule from Internal and VLAN network to the Internet.

I started monitoring on ISA, and found denied requests on the Firewall Client negotiation port. I made an new rule allowing the Firewall Client access to the negotiation port on ISA ( I do have an all outbound rule stating that in the first place?? ) but i still not work.. ?

Can U help me please? 

Thx in advance.

Hi,

Make sure all the subnets that you have are defined in the Internal Network. You have a network within and network scenario.

HTH,

Ashok.
