851 Firewall Error using SDM or SDM Express

[bmathis]

When trying to enable the basic firewall on the 851 with SDM or SDM Express I receive the following:

Preparing commands for delivery...

Submitting 283 commands, please wait...

class-map type inspect imap match-any sdm-app-imap

Error detected at this command. Click OK

Here are the SW versions

IOS Version: 12.4(15)T5

SDM Version: 2.5

I have seen a couple other posts on this forum with very similar issues, but none of them have solutions posted...

Thanks!

Brady,

The problem that you are having are limitations on your router. The 851 does not support the zone based firewall. This feature is supported with the advanced IP services IOS... which unfortunately is not available for the 851. There is a known bug within SDM that tries to configure the zone based firewall even if the router doesn't support the Zone-based firewall. If you do find this a necessity I would recommend the 871 router that will support the firewall and many other features.

HTH,

Mark
