Anyone in the UK that can offer any assistance with setting up my new router? I thought using SDM would be fairly straight forward (I know little CLI) but I'm struggling to get the LAN / WAN up and running?
Be sure you use the SDM to setup ACLs for you... If you do the Firewall - Low method, that is usually sufficient for general use. If you do not configure ACLs, all your ports will be visible on the internet.
You will need to be registered I think (not sure if its a separate account from support forums). When downloading it will ask for username/password, just use your cisco login information.
Setting up the ACLs from scratch is kind hard in my opinion, but I'm still new to ACLs, and I'm still in school (we haven't covered ACLs yet).
ACLs were the only thing I setup from SDM (Firewall option = ACLs); I used the Firewall - Low option, and it did exactly what I wanted it to -- closed up all my ports from internet access. Configuring the ACLs with SDM is a breeze, just a few clicks and you're done. Be sure to have the following lines in your running-config to connect via SDM:
ip http server
The SDM will connect to any interface IP Address through a vty line.
If you need any other CLI help with the 851, I can probably help.. I just setup my 851 recently.
