Hi, I have setup a server host running FreeBSD2.2.5 with IPFILTER and
config its IP address with 192.168.1.1. The server can run ppp auto to 
my ISP to get an dynamic IP address. Then, in my LAN, I config some hosts
with 192.168.1.* netmask 255.255.255.0. Ping the server works okay. But
when I telnet to the server, I must wait for a very long time to make the 
connection. When connected, everything works okay. When the server has
connected with the ISP, the telnet connection between the client host
and the server will make smoothly. Why? 

PS. I have config the server with the tcp_extension=NO
