IOS recommendation 1720 WIC-1ENET

[beekerc]

I have a Cisco 1720 router with two WIC-1ENET ethernet cards, one connects to a Cisco 678 DSL modem, one to a perimeter DMZ network and the built-in FastEthernet port to the private network. I did have a WIC-1ADSL card but found out it couldn't talk to my DSL provider's DSLAM so I had to keep the DSL modem.

my question is what is the latest, greatest and most stable release of IOS that supports two WIC-1ENET's and has the following features

IP, FW, IDS, Plus, IPSec 3DES

12.2(2) XJ supports two WIC-1ENET's but 12.2(4)T only supports one.

Thanks

Brian,

The 1720 started to support 2 WIC-1ENETs in 12.2(8)T, the latest in this train is 12.2(15)T1 which requires 48MB DRAM and 16MB of flash for the IP/ADSL/FW/IDS PLUS IPSEC 3DES feature set. I would rather go with the 12.2(15)T1 instead of the XJ train. I hope this answers your question.
