Hello,

I installed FreeBSD-4.6 on HP Vectra PC. I configured
this machine as NAT gateway.

Connection diagram:

LAN-------FreeBSD IPFILTER/NAT/DHCP----ADSL modem-----ISP

PPPoE and IPFilter/NAT/DHCP working normal.

Problem is Windows 95/98/98SE users can to go through FreeBSD gateway
machine, but Windows 2000/XP sometimes working, sometimes can't. Sametime
if can't work Windows 2000/XP stop to access LAN servers, shared
resources.

Strange thing, I can to ping from Windows 2000/XP PC to outside network
hosts. If sometime I refresh IP address from DHCP, then I can to access
some website after few minutes it stop.

If I try to ping using domainname of outside host then impossible. But
from FreeBSD gateway machine I can to ping IP/domain name of hosts.

I check DNS servers of our ISP and it is working normal.

I don't know this mailing list correct or not.

Any suggestion?

Thanks,
Balgaa
