You can increase the MTU to 552 by adding: options "SLMTU=552" ...to your kernel config file. Increasing the MTU higher than this is too difficult to explain in a limited amount of time. MTU's higher than 552 won't normally buy you anything because the negotiated MSS for non-local networks is limited to 512 bytes. -DG
