Hi All, Does anyone know if this is possible and if so, can you please provide some pointers. Network 192.168.0.0 WebManager Server 192.168.0.7 for content filtering and blocking ISA Server 192.168.0.11 - only 1 Nic Lucent Firewall 192.168.0.4 providing NAT Trend WebManager needs to use a proxy server and therefore we bought ISA as proxy 2 was not available. We installed ISA in caching mode only. All workstation have no default gateway. All browsers point to the webmanager server port 8080. Webmanager uses ISA server as its proxy. The ISA server default gateway is the lucent firewall. This works 100% for browsing and FTP. The problem I have is that I need to open ports 15000-15015 for internet banking, but maintain the use of Trend WebManager What I have tried. 1. Install ISA in integrated mode. 2. Create protocol definition for ports 15000-15015 3. Create protocol rule for the definition I created. I suppose my real question is, can ISA work in integrated mode with only 1 NIC? BTW, I tried this setup with Proxy 2 and it works. > Regards, > > Warren van Eyssen > Systems Engineer - CNE, Citrix CCA, Compaq ASE, IBM PSS > Lan Workgroup Solutions > Tel: (021) 683-5390 > Fax: (021) 683-9141 > Mobile: 082-892-6960 > Email: warren@xxxxxxxxx >
