Abstract
A bastion host is provided for a local area network (LAN). The bastion host processes packets to be transferred from the LAN to a wide area network (WAN). The bastion host intercepts packets originating from a host on the LAN, the packets being destined for transmission over the WAN, extracts bits from predetermined fields from each packet header to form one or more blocks for translation, masks bits from the one or more blocks that vary rapidly packet to packet, applies a predetermined encryption algorithm to translate the one or more blocks after masking; and reinserts bits from the translated block back into the packet header.
