While debugging connectivity issues on my recently installed CyberCity ADSL line, I came to suspect the ZyXEL router supplied to me by the ISP.
Erwin kindly offered to lend me a good old Cisco SOHO 77 ADSL router to test with, which meant I had to find out how to actually configure this device for use with CyberCity.
It didn’t take long, though – below my configuration for reference:
- dsl654321 is my CyberCity user name
- 11.22.33.44 is my public IP address
- The example configuration contains a static PAT for all ports to 192.168.0.2

Before I got Fiber to the Home, I had a ZyXEL Prestige 642R for ADSL. Which I never had trouble with, other than sometimes having to reboot it after the link had gone down and the modem showed LCP errors (I guess sometimes it didn’t recognize that everything was okay again).

This is a ZyXEL Prestige 660HW-D1 (actually, it’s my second 660HW-D1 – CyberCity kindly sent me a new one after a technician had measured the raw copper phone line as being “nearly perfect”).
My connection problem remains, though – even with the Cisco SOHO 77 – so I’m guessing the problem lies at the DSLAM (which means I’ll have to make yet another call to CyberCity support :-))
