A method of supporting mobility between access domains (50-1, 50-2) in an Internet Protocol network, said method comprising the steps of: - a mobility manager maintaining a database of currently attached devices and their current access domain location; - said mobility manager detecting, for a device registered in said database, a change of access domain from a first access domain to a second access domain by monitoring connection maintenance signaling related to said device; - said mobility manager arranging for, in response to said detected change of access domain, a reconfiguration of the network, by performing remote router configuration, to forward traffic destined to an IP address of said device in said first access domain to a new location in said second access domain, thereby allowing said device to keep said IP address when moving between access domains, wherein said step of arranging for a reconfiguration of the network comprises the steps of: establishing a first static route entry, in one of an access router of said first access domain and an Internet gateway of the network, for the destination address of said device directing to a tunnel leading to an access router of said second access domain; and establishing a second static route entry, in the access router of said second access domain, for the destination address of said device pointing to a directly connecting interface to which the device is now attached, wherein said mobility manager is implemented in a single node or block (10; 20; 100) in the network. - a mobility manager maintaining a database of currently attached devices and their current access domain location; - said mobility manager detecting, for a device registered in said database, a change of access domain from a first access domain to a second access domain by monitoring connection maintenance signaling related to said device; - said mobility manager arranging for, in response to said detected change of access domain, a reconfiguration of the network, by performing remote router configuration, to forward traffic destined to an IP address of said device in said first access domain to a new location in said second access domain, thereby allowing said device to keep said IP address when moving between access domains, wherein said step of arranging for a reconfiguration of the network comprises the steps of: establishing a first static route entry, in one of an access router of said first access domain and an Internet gateway of the network, for the destination address of said device directing to a tunnel leading to an access router of said second access domain; and establishing a second static route entry, in the access router of said second access domain, for the destination address of said device pointing to a directly connecting interface to which the device is now attached, wherein said mobility manager is implemented in a single node or block (10; 20; 100) in the network. establishing a first static route entry, in one of an access router of said first access domain and an Internet gateway of the network, for the destination address of said device directing to a tunnel leading to an access router of said second access domain; and establishing a second static route entry, in the access router of said second access domain, for the destination address of said device pointing to a directly connecting interface to which the device is now attached, wherein said mobility manager is implemented in a single node or block (10; 20; 100) in the network.
