I use SDM primarily to configure our CISCO routers, but we also have SmartNet's in place for the difficult CLI stuff.
We've just replaced our aging main router (1721) with a 2811. Its all configured, but the firewall is no longer something I'm confortable with.
The old router used the traditional CBAV firewall, and I was happy with it, very straightforward to use.
The new router however is completely different, the interface and the way you configure basic rules.
Is there any specific training and/or documentation on this subject? As an un-trained, CISCO novice, I am finding configuring our router with the same access restrictions as our last one a nightmare!
Anyone recommend a training course or learning resource?
You can go for CCNA-SECURITY training, you will have all the knowledge necessary for Zone-policy firewall using SDM. You might even try self study using cisco press books for CCNA-SECURITY, it has all the zone-firewall topics plus step by step configuration link below :-
