Problem with dhcp and ISP.

[Todor Dragnev]

Hello, 
I have the problem with my ISP and network settings received from ISP DHCP 
server.

with dhcpclient I get:
IP address for interface xl0: 213.x.y.77 netmask 255.255.255.252
default gateway: 213.x.y.77

Yes, IP address on interface and gateway are the same.
The interesting part is that with these settings on Windows and Linux I have 
access to Internet. But FreeBSD refuse to work. What must be done to have 
access on FreeBSD v5.4.

I found that the router IP address is 192.168.1.1 and if I up manually 
xl0 alias 192.168.1.2 netmask 255.255.255.252, 
change default gateway to 192.168.1.1 and make ipnat
map xl0 192.168.1.2/32 -> 217.x.y.77/32 
freebsd box now can use Internet. 

But I want use DHCPclient for xl0, because ISP offten change network settings. 
Does anyone known the solution for this problem.

Thanks,
