Can a Cisco 1720 router support two separate networks and share a dsl internet connection?
My network is currently using a simple dlink dsl router for internet connectivity. I need two subnets and I need them to use the same dsl connection for internet access. I have a win 2k domain with 24 clients. I have a 1720 router. What kind of WAN connection do I need? (Do I have to have an ADSL WIC card or will something else work?) Can I use an ethernet card in one of the WIC slots so that I can connect a second network? Help.

I just looked at a router on ebay that claims to have dsl/cable connectivity but it only has a DSU T1 WIC. How is this possible? I have seen this more than once. I am confused? My 1720 has a dsu t1 wic. If I need to buy a card, do I buy a enet wic or a adsl wic? which is cheaper and which is easier to setup. Thanks.

I can get a WIC1E from another company for free. The only problem is that it is 10baseT. Is this enough bandwidth for a WAN connection supporting 24 users? Users regularly connect to the internet mostly for email and surfing. I sometimes use this connection to download updates for the computers on the network. Also is a WIC1E the same as a WIC ENET?

1720 does NOT support VLANs (I know this because I have one)
"The Cisco 1721 offers many significant feature enhancements over the Cisco 1720 router, including: greater memory architecture, faster processing, and 802.1Q VLAN support."

I am attempting to set up two VLANS on a Cisco 2924xl and have a Cisco 1720 router. I can only bring one VLAN up at a time. How can I use this single interface to feed both VLANS. My router doesnt seam to have subinterface capabilities. Am I simply two sheets to the wind?
As far as I know you're going to have to either purchase another interface, or buy a different router. It may be possible if you have enough flash/memory, but I know 802.1Q is not supported on my 1720 with the basic feature set.

A few questions:
Will the cisco 1720 support VLANs? If yes wouldn't I need switches that also supported VLANs? I do not have this. Currently I have 1 hub and 1 cisco 1912 switch that does not support VLANs (standard ed.).
I currently have a modem attached to my dsl router WAN port. What would my modem attach to on the 1720, I assume a ENET WIC? Thanks for your help.
