Unfortunaelly the .cz firmware for wl-500gx contains a ppp not compiled with support for active-filter.
I guess even using iptable I still not able to stop internet since idle time is never reached due to misc incoming packages.
Could it be possible to include ppp filtering in a new firmware or provide a ppp package with support for acrive-filter (I'm interested in outbound keyword).
Please help me or provide me an alternative to be able to ignore incoming packets when dial on demand is used with pppd.
Thanks a lot
