I just bought 2 Cisco 1841 routers. I bought them because I have to configure a T1 line between the 2. However, I just purchased the standard image without any type of crypto support. Initially this wasn't a problem, but now it is. I would like to setup ssh to login to the routers, and I would also like to setup a VPN tunnel between the 2.
I have been looking around, and I have found the following part #: S184ASK9-12308T
This is for the Cisco 1841 IOS Advanced Security. However, it looks like it's for IOS software release 12.3(8)T4.
I need the advanced security IOS to utilize the VPN tunnel, but I'm pretty sure that isn't the latest software release (the software that came with my units is version 12.4(1c), release software (fc1)). So here are my questions:
- Does anybody know the latest IOS release that will support what I want to do on my Cisco 1841 routers?
- I have also been reading about the VPN accelerator cards for the 1841, I don't think I need to purchase one of these to support a VPN tunnel, and I would rather just setup a VPN with the software. Can somebody confirm that I don't need to purchase 1 of these?
