Client computer has only one nic configured with
ip: 192.168.1.3/24 gw: 192.168.1.4 dns: x.x.x.x OS: winxp
'Gateway' computer has only one nic configured with
ip: 192.168.1.4/24 gw: 192.168.1.100 dns: x.x.x.x OS: winxp
x.x.x.x is an ISP dns provider
192.168.1.100/24 is the lan interface ip of a typical router/AP that has a public IP on the wan interface and does NAT for lan clients.
Client computer has normal internet conectivity.
route print in Client computer lists a number of entrys like this for every host Client is/has connected to:
220.127.116.11 255.255.255.255 192.168.1.100 192.168.1.3 xx 18.104.22.168 255.255.255.255 192.168.1.100 192.168.1.3 xx hhh.hhh.hhh.hhh 255.255.255.255 192.168.1.100 192.168.1.3 xx hhh.hhh.hhh.hhh 255.255.255.255 192.168.1.100 192.168.1.3 xx
hhh.hhh.hhh.hhh: other host that computer is/has connected xx: can't remember metric atm, nothing special I think
Looks like some routing protocol is involved but this is new to me and not precisely a standard setup.
Edit: This is my question and maybe it is not clear: The static point-to-point routes appear automatically on 'client' computer as you browse or open connections. The kind of answer i'm expecting is like this: "Gateway computer seems to be running X software/protocol/service that provides the static routes automatically to Client. Client is also probably configured with X mode/protocol/software"
