My desktop PC runs Win98 SE and connects to an Epson printer via a wired printer port. I'm getting alerts from ZA on that PC when I print to this printer from a laptop, which is running XP and is connected via a wireless network (Linksys WRT54G wireless router), but the printing works anyway.

I already have the IP range 192.168.1.101/255.255.255.0 in the Trusted zone, which I thought was enough to cope with the router itself (192.168.1.1) and the range it assigns to clients (192.168.1.100 - 192.168.1.149). I can't find any references to higher IP addresses in the router's own configuration pages. However, during printing ZA blocks "access to your computer (NetBIOS Session)" from 192.168.92.1 and from 192.168.117.1. Here's a short extract from the log:

FWIN,2007/10/22,18:26:50 +1:00 GMT,192.168.117.1:2894,192.168.1.101:139,TCP (flags:S)
FWIN,2007/10/22,18:26:50 +1:00 GMT,192.168.92.1:2895,192.168.1.101:139,TCP (flags:S)
FWIN,2007/10/22,18:26:50 +1:00 GMT,192.168.117.1:2898,192.168.1.101:139,TCP (flags:S)
FWIN,2007/10/22,18:26:50 +1:00 GMT,192.168.92.1:2899,192.168.1.101:139,TCP (flags:S)

It goes on like this, with at least 6 lines per print, sometimes a lot more, incrementing the source port numbers somewhat irregularly as above.

As I said it doesn't stop the print working, but the alerts are irritating, and I'm uneasy about just adding these two extra IP addresses to the Trusted zone when I don't know what they are. Any ideas?
