Hello.

I have 3 options in the webinterface, that i cant find any help to.

Does anyone know what the options do

1: Filter multicast
2: Filter internet nat redirection
3: Filter IDENT (PORT 113)

All 3 have enabled or disabled

Thanks
Regards
Brian.

What model Linksys do you have?

Filter means "block" in Linksys-speak.
Multicast is 224.xxx.xxx.xxx thru 239.xxx.xxx.xxx.  These allow for
highly efficient distribution of duplaced data (like streaming video)
to multiple recipients by sending the data simultaneously to each
recipient, rather than using unicast packets to feed each user
individually.  If you do NOT want such traffic, enable the filter.

That's a wierd one.  Linksys claims that it:
  (...) disables local LAN users from accessing port forwarded
  services in the router.
whatever that means.  That makes no sense.  When I last tinkered with
it on a BEFSR41 router, it seemed to prevent accepting WAN packets
that pretend to be from the LAN side.  However, I'm not sure and
didn't do much testing.  Probably a good idea to have it on.

IDENT is a very old and crude method of authenticating a system.  It
also has some nasty security problems.  Some mail servers seem to
require that IDENT is running even though it apparently ignores
whatever is returned.  If your mail provider does not require IDENT, I
would block, er... filter it.

Well, they're either enabled or disabled, as both and neigher are not
valid options.

Hi Jeff.

Thanks for clearing up the options.
Its a BEFW11S4 V4.

Do you or others here know a good official/unofficial Linksys forum for
wireless?
One told me about a very good unofficial forum, but forgot the link to it.

Mine hangs about once per week.  That's why I have it.  I replaced it
for a customer.  The problem is that the router can be hung from the
internet side with various exploits. 
Run:

and see for yourself.  Targa3 hangs my BEFW11S4 v4 quite nicely as
does one other (I forgot which).
