Hi Jim, Thanks for ur Link. I searched the link . But i couldn't get solve my problem. I don't have Modem in My computer. I want to configure my ISA not use my Modem, But i want to use my LAN(NIC card) to connect to the internet thru Firewall. May be like configuring ur browser to use proxy to access the internet. Hope u r clear Now. I don't think it's possible. But this is possible in Gauntlet5.5. That's why i am expecting the same In ISA also.

ISAserver.org has many documents for setting up ISA, including how to set it up for dialup use. http://www.isaserver.org/pages/tutorials/configuring_isa_server_dial_up_conn ections.htm Jim Harrison MCP(2K), A+, Network+, PCG ----- Original Message ----- From: "B.

I searched on the internet also. But there is no document for my problem. I want to use my firewall in my ISA to access the internet.(on behalf of modem i want to use my firewall in my ISA to connect to the internet). Tell me whether it is possible in ISA or not. SO that i can go for specific search. Thanx... Saravanan -----Original Message----- From: Jim Harrison [mailto:jim@xxxxxxxxxxxx] Sent: Wednesday, July 18, 2001 6:49 PM To: B.

Take a deep read in the ISA help file and the Learning Zone on isaserver.org. Jim Harrison MCP(2K), A+, Network+, PCG ----- Original Message ----- From: "B.
