Help with dial-up to multiple ppp servers
Hello all,

I am trying to establish two ppp connections using chap authentication over dial-up. I am using the generic connect scripts and can connect to the first server but when I try to connect the second while the first one is connected there is a chat timeout that occurs.

Any assistance would be greatly appreciated.

Thank you.

Do you have any PPP client logs...? Which stage it times out ? LCP or IPCP ?

I see your connection-1 also using ppp0. If you say that Connection-0 is active, ppp0 should have been assigned already to Connection-0.

Are you able to connect to connection-1 standalone without connection-0 ?

yes - connection 1 connects, hang-up, then connection 2 connects.

I am trying to figure out why a ppp1 interface isn't being created when the second connection is initiated.

If Connection-0 hangs up by the time Connection-1 is initiated, then using ppp0 is ok...you may probably need to recheck the dial-up configs(number)

somewhat defeats the original question posted; multiple concurrent connections is needed e.g. parallel connections. They are remote devices

Ok by using unit [n] in the pppd options the interfaces are incremented e.g. ppp0 (connection1) and ppp1 (connection2) but connection 2 chat times out.

figured it out thanks.
