I've got a 3640 router with 2 dialer interfaces configured with PPP to fire up an ADSL modem (each interface has it's own modem, so 2 in total). Everything was working perfectly until I upgraded the IOS from 12.2 to 12.3-1a. Now the router will only bring up the second dialer but won't even try to fire up the first one. When 12.2 was put back on, the router worked fine again. What is in 12.3-1a that's causing this and how do I work around it?
Thank you for any advice you can offer,
