I am trying to configure my 871 to work with a netopia DSL router I have tried to setup the cisco with the static ip provided by bellsouth with gateway and subnet I have also tried to configure the 871 with the pppoe username password and chap/pap prot setting in the netopia router. I have also tried to assign the 871 to accept dhcp on the wan fastethernet4 port all of the above settings tried where on the same port. Any help would be great what I am trying to do is get the 871 to be my outer most post and setup the site to site vpn. Thanks for any help in advance. I am new to cisco but not small business and home networks I usually use linksys routers and they are pretty straight forward with settings. I am using the SDM software that came with the router and I also am comfortable with CLI commands if need be.
I have this problem too.
