please take a look at examples in rfcomm_pppd(8) man page. you might want
to start with clean ppp.conf and make Bluetooth stuff work then add your
existing configuration.

up until this section everything looks good.

this section tells me that remote side wants to open RFCOMM connection on
DLCI 2 (RFCOMM channel 1), but FreeBSD rejects this connection (most likely
because nothing is listening).

did you run "sdpd"? you need to run "sdpd" and then register service with
"sdptool". also you can verify that service has been registered by issuing
"sdptool browse ff:ff:ff:00:00:00" and look for LAN service.

aha! this is the problem. you misused "-a" option. in server mode "-a" tells
rfcomm_pppd(8) on which *local* BD_ADDR it should listen. it seems that you 
have specified *remote* (mylaptopaddress) BD_ADDR. this (*remote*) BD_ADDR
does not exists on FreeBSD, so connection will never be accepted.

in general server application should listen on ANY BD_ADDR, i.e. accept
connection via any local device. so what you should do is remove "-a"
option completely, .i.e.

rfcomm_pppd -s -C 1 -l bluetooth

this will make rfcomm_pppd(8) accept connection from any local device.
its all in the man page.

can you discover services on your MAC laptop? do you see FreeBSD? do you
see LAN service on FreeBSD? if not then you did not setup "sdpd" on FreeBSD
properly.
