Hi all, I solved the problem about ppp negotiation on the previous thread now a strange thing happened. The configs are below.
host A--newyork-----albany---host B 10.1.3.2 10.1.1.2 Everything works fine ppp authentication and connection from aux. But while they were connected from aux if I tried to ping from host A to host B I can not ping B. But newyork router can ping Host B. I got crazy and changed my configs so many times and I find out that if I add the command dialer string 125 to Albany router bingo, I can ping host B from host A but if I don't add the command I cannot ping host b from host A. And also if I delete all the dialer commands froms albany routers config, again I can ping host B from Host A. As I know Dialer on demand shouldnt block the pings. Because with or without the dialer commands the show ip route command is same for Albany. Why is it happening? Any idea? Best regards, newyork#sh run Building configuration...
