WAP11 connecting to a BEFW11S4 router

I have purchased a WAP11 Access Point to try and connect a remote LAN
to the BEFW11S4 router, which is sharing an ADSL internet link.
I have looked at the posts on several newsgroups and all I could find
is that this would not be possible.
I went to Linksys site and used the support chat. The person on the
other side of the chat confirmed that WAP11 only talks to another
WAP11.
Well, it happens that I am posting this message from my PC in the
remote LAN using the ADSL link on the other side of my house wirelessly
via the BEFW11S4 router.
This is what I did (no rocket science):
1- router is using MAC address filters, so I configured WAP11's MAC
address into the router's MAC list.
2- WAP11 is configured in mode Wireless Bridge (you have to inform the
MAC address of the BEFW11S4).
Voilá!
Notes:
WAP11 v2.8, firmware 2.05 (out of the box)
BEFW11S4 v4, firmware 1.52.02 (downloaded and upgraded from Linksys web
site)

Good luck!

PS: Linksys, please know your products better...
