Multilink ISDN Connection Problems

[jim2z]

Hello everyone,

I got a weird problem with my multilink (2 channel) ISDN dial-up connection. When I try to connect to my ISP, the connection process seems to work alright, but I can't access anything outside my home lan. The connection authenticates ok, I can see the dial-up connection icon in the taskbar, two B channel modem LEDs are lit. The weird thing is that, I can't see the connection/adapter when I run ipconfig /all. I can see an IP assigned to the connection in the connection status>details tab, though.
Connecting only 1 channel works fine.

Brief config info:

OS: Win XP Pro

Modem: Zyxel omni.net plus (serial)
settings: modem protocol PPP 128k, enable HW flow control, enable modem error control, enable modem compression – all ON

Connection:
PPP: enable LCP, enable software compression, negotiate multi-link for single-link conn. – all ON
TCP/IP: obtain IP automatically, obtain DNS automatically
Advanced:
General: use default gateway on remote network, use IP header compression - ON
DNS: append primary and connection specific DNS suffixes a append parent suffixes of the primary DNS suffix ON
WINS: enable LMHOSTS lookup, disable NetBIOS over TCP/IP

I would appreciate any suggestions or possible solutions.

Thanks,

jim2z

Have you confirmed that your ISP supports channel bonding?
