Internet access & firewall

[4candles]

Can anyone explain this please?

Using a Linksys ADSL2MUE modem, Internet access is fine. It has NAT firewalling, but I use ZA Free anyway for additional outgoing security.

If I then install a dial-up adapter for back-up, the ADSL2MUE logs on OK, but I can't access the web unless ZA is running. I can then shut down ZA, and access is still OK!

Obviously, it's no big deal, since I want to run ZA anyway, but I'd like to know why this happens. And, if ZA should irretrievably crash or get corrupted, presumably I wouldn't be able to aceess the net to download it again?

OS is Win98SE.

Thanks Marcus, but I've no reason to think it's a problem with the modem. I only mentioned the model to indicate that it behaves like a router, and installs itself as part of a LAN, rather than the pseudo-dial-up fashion of most USB ADSL modems.
