Has anyone else experienced PPP (LCP) problems when using a 37xx series router as a RAS. More specifically the actual problem we see is intermittant connectivity when a client attempt a dialin. Some succeed,some fail. The problem exists for both PSTN and ISDN dialers (pstn onto MICA modems). If i swap out the router and use a 3640, with the exact same config and exact same software all works fine. I have even replaced the 3745 for another 3745 but get the same results.
Any thoughts, comments would be useful..
