I currently use an 837. In addition to the dialer config, I have acl's, port forwarding etc.
I've read that the 857 and 877 are 'fixed-configuration routers.' I'd like to upgrade to one but need to be able to configure it via the IOS. '
After two days of looking, I still can't find the answer. Is it possible to 'custom' configure these or are they just plug and play type routers? Thanks.
