Are you using PPP or Frame Relay encapsulation? Check the encaps settings carefully; if PPP, is compression enabled on one side but not the other, etc... It sounds like you might have an encapsulation error. Set aside the fact that it's DSL for a moment and check the upper layers. >The pipeline originally used RFC1918 addresses on the ethernet interface, >and was running Network address translation. I've not used the pipeline NAT >implementation for anything before, so I wasn't sure if this was the cause. It shouldn't be a problem with recent code. >I also couldn't gain telnet access to the pipeline when NAT was enabled.

Adding >a static mapping so that port 23 points at the pipeline's ethernet interface >address does not provide remote access either. A static mapping _should_ work to get you telnet access. >The code revision on the Max is: 8.0.3, the pipeline is running 7.10.8. So presumably this is a DSLPipe-HS or -HST? Those are decent boxes and we have them in the field with no problems. We are running 7.10.5.
