Apparatus having corresponding methods and computer programs comprise a first port comprising a first transmitter to transmit a first packet to a first network, wherein the first packet identifies a first maximum size; a first receiver to receive second packets from the first network, wherein each second packet has a first size less than, or equal to, the first maximum size; and a second port comprising a second transmitter to transmit third packets to a second network, wherein the second network has a second maximum size greater than the first maximum size, wherein each third packet has a second size that is less than, or equal to, the second maximum size, and wherein each third packet comprises one of the second packets and a tunneling protocol header having a size that is less than, or equal to, a difference between the first maximum size and the second maximum size. |
