Consumer routers suck, plain and simple. Personally I'm used to the rich features Cisco routers provide. Of course, I am biased, however it seems a common goal to get broadband connections working on Cisco routers.
ADSL connections are a pain, they're usually finicky and difficult to troubleshoot. This post contains the configuration required for a sky ADSL connection.
Solution / Configuration
Below is the required configuration (non complete for security reasons).
interface ATM0 no ip address no ip redirects no ip unreachables no ip proxy-arp no atm ilmi-keepalive pvc 0/38 encapsulation aal5mux ppp dialer dialer pool-member 1 ! !
interface Dialer0 bandwidth 8000 ip address negotiated no ip redirects no ip unreachables no ip proxy-arp ip mtu 1492 ip nat outside ip virtual-reassembly in encapsulation ppp ip tcp adjust-mss 1460 dialer pool 1 dialer idle-timeout 0 dialer-group 1 ppp authentication chap callin ppp chap hostname [email protected] ppp chap password 7 0502081C354D4205 ppp ipcp dns request no cdp enable ! !
This is the meat of the configuration required for Sky ADSL. Obviously other configuration is required for LAN services etc. NAT is also required however "standard" overload configuration is fine. Other configuration is out of the scope of this post.
The specifics of this connection are the username & password required for the connection to come online. The PPP credentials are as follows:
Username: [email protected]
This username and password appears universal to Sky broadband, even new installations. I am assuming that Sky performs authentication based on the same mechanism that BT uses - the subscribers phone number / connection.
