I my networking we have one NT server, 10 Workstations, one router and one gate lock. In this network thru router we access our HO. Such that they have assigned an ip address range 192.168.8.1 to 192.168.8.200. So I should assign this ip to the TCP/IP of the Server and worskstation. Last week we bought GateLock and thru that our workstations will access internet and it will protect from viruses. It has its own DHCP server such that they have given instruction to setup all our workstations as obtain IP address such that they can access internet. Now the problem starts. For gate lock they have assigned ip range from 192.168.253.1 to 192.168.253.100 so If I use obtain DHCP then I can't get into my own network and if I change the range of my NT server from 192.168.8.1 to 192.168.253.1 then I can't go thru the router to my HO. Can anyone help me in this how to solve it so that I should access the gatelock, my nt server and the router also. Thanks in advance.
