I have an ADSL line in which I was given a range of fixed public IPs (xxx.xxx.xxx.xxx 255.255.255.248), a Point-to-Point IP number (yyy.yyy.yyy.yyy 255.255.255.252), a VPI (8) and a VCI (35). There is no telephone number to call, no username or password to do any ppp authentication. I am trying to configure a Cisco 827 to work on this line. I have tried two types of configuration so far.
In one, I used an encapsulation of aal5mux ppp dialer on the pvc, with the public IP gateway number (xxx.xxx.xxx.xxx) on the dialer interface, and the PP IP (yyy.yyy.yyy.yyy) on the atm interface, On the ethernet interface, I use NAT. See configuration 1 below.
The result of this configuration is UP, UP on the eth0, atm0 and dialer1 interfaces and UP DOWN on the (2) Virtual-Access interfaces.
If I ping the router from outside (either xxx.xxx.xxx.xxx or yyy.yyy.yyy.yyy), I see the RX light flashing away, and the router stats show the packets received, but no response is sent. There are no atm debug errors, nor ate there any pvcd events logged in the debug atm pvcd.
In the other configuration, I used a pure bridge with the public IP dateway number (xxx.xxx.xxx.xxx) on the BVI interface and the PP IP on the atm interface, with an aal5snap encapsulation on the pvc. See config 2 below.
The result of this configuration is UP, UP on the eth0, atm0 and bvi1 interfaces; there were no virtual-access interfaces (no great surprise).
Again, there was the same result with a ping from outside, but that a non RFC 1577 packet was received (so it is not a snap protocol?)
The telephone company says that the line is fine.
I am at a loss as to what to try next. Any ideas?
Mike.
