Hello- My ISP drops my connections after a ridiculously short inactivity. Apparently the afilters are the way to keep the connection alive, however, the documentation does not say what the following do: # # KeepAlive filters # Don't keep Alive with ICMP,DNS and RIP packet # set afilter 0 deny icmp set afilter 1 deny udp src eq 53 set afilter 2 deny udp dst eq 53 set afilter 3 deny udp src eq 520 set afilter 4 deny udp dst eq 520 set afilter 5 permit 0/0 0/0 What actually happens, especially where performance is concerned? Would it be better to send a ping packet every few minutes? Thanks -Glen To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
