I have very little experience on this so I am asking to see if this is even possible. I have 4 different ADSL connections that each one is connected to one access point so I have 4 total different lans. I provide free hotspot on each access point (same SSID) and the user roaming from one access point to the other as they move into the area. (The area is a long road and the distance beetween each AP is about 100m).
Anyway i saw on the modems the option for dhcp relay so I am asking this.
Can I build a central server (internet accessable) with ubuntu and dhcp server on it and setup the modems to use this as DHCP server? So the user keep the same IP as it moves from one AP to the other. All adsl modems will have the same IP so the gateway will remain same for all networks. I dont know if this is good so I am asking this question just to tell me what is the best way? To build a central server or to leave each modem act as dhcp server
Because my English are not very well I hope you understand my question
Thanks a lot!
