no mention of igmp!
any idea's ?
from reading the pppd man page, it could easily be solved if i ran BSD as
pppd allows filtering on BSD systems!
unless you can see what the problem is, can i make an enty in /etc/host.deny
to prevent these igmp packets since they come from a specific address?
eg
all:213.105.116.221
can i find out if this ip address provides a service i might use?
uploading web pages?
will this cause problems with other services?
