Greetings, I have an OpenBSD 3.9-RELEASE wireless gateway using ral(4) in Infrastructure mode to provide a wireless LAN secured using ESP. It is connecting to the internet via IPv4 using kernel ppp(4) and pppd(8) - not userland ppp(8) - and routing to IPv4 wireless clients using NAT in pf.conf temporarily until I can arrange for ADSL.
After an initial burst of activity routed connections slow down to something worse than a crawl. I have confirmed that activity between the gateway and the internet i.e. just ppp(4) performs as expected, and similarly activity between the gateway and wireless clients i.e. just ESP over 802.11b performs as expected. This leads me to hypothesise that the cause must be in the routing between the two networks. Could this be a fragmentation issue. If so/not does anyone have any suggestions? If my dmesg, pf.conf or IPsec configuration files are required for diagnosis please let me know. Thanks in advance, Damon
