Abstract
A method of handling mobile entities in a firewall, wherein a first mobile entity table comprising identifiers of mobile entities, which are active in a firewall, and a second mobile entity table comprising identifiers of mobile entities, which are active in a predefined set of other firewalls and identifiers of corresponding other firewalls, are maintained in the firewall. A new mobile entity, which is not currently active in the firewall, is detected, after which it is found on the basis of the second mobile entity table, if the new mobile entity is currently active in another firewall. If the mobile entity is currently active in another firewall, state information related to the new mobile entity is queried from the another firewall, and stored in the firewall to be used for processing data packets from/to the new mobile entity.
