When ppp is started, these messages are recorded in the syslog. ... pppd[n]: Couldn't set pass-filter in kernel: Invalid argument ... pppd[n]: not replacing existing default route to eth0[192.168.1.1] ... pppd[n]: Cannot determine ethernet address for proxy ARP Routing fails, of course. Does anyone recognize the problem or have a suggestion? Can anyone explain the complaint about the pass-filter? Thanks, Peter Easthope http://carnot.pathology.ubc.ca/
