The problem that I have is that I travel everyweek and hook my laptop

That said, perhaps there is a way (I think there is) that I can force my
DHCP server at home to always provide the same internal IP address to my
laptop right, by specifying the MAC address or something?

Yes, all DHCP servers should have a way to reserve an IP by MAC address, 
and most will give the same MAC the same IP for some reasonable length 
of time anyway unless there is a big turnover with the lease expired. 
Anyway, if you just connect to the backuppc web interface from the 
laptop itself and request the backup, it will find you - and keep 
working at least until the IP changes.

laptop1 is a DHCP host, and I don't know its IP address. I checked the netbios name of 192.168.15.155, and found that that machine is not laptop1.

Until I see laptop1 at a particular DHCP address, you can only start this request from the client machine itself.

That's my issue, but will look into trying to reserve a specific address for this laptop as that's probably an easier solution to the problem, at least for me :)
