>Environment:
Using iijppp to filter packets.
>Description:
The man page for ppp implies that a filter of the form:
<action> tcp estab
should work. However, it is rejected as a syntax error by the parser.
>How-To-Repeat:
Put a line such as
ifilter 0 permit tcp estab
in /etc/ppp/ppp.conf
>Fix:
*** filter.c 1998/01/23 03:38:16 1.1
--- filter.c 1998/01/23 03:38:33
