I'm not 100% certain about this, but I believe you must recompile the kernel with a higher setting of the value for TUNMTU, defined in the header file "/usr/src/sys/net/if_tun.h" in order to pass > 1500 byte packets to the tunnel interface. Then say "set mru 1800" or whatever to ppp. Also check out the definitions in "/usr/src/usr.sbin/ppp/hdlc.h". -Archie _______________________________________________________________________________ Archie L.
