I'm having a similar issue. I was running c1841-advsecurityk9-mz.124-18.bin until last night PPTP with MPPE auto required was working perfectly After upgrading to c1841-advipservicesk9-mz.151-4.M5.bin I have to set to ppp encrypt mppe auto And change the PPTP clients to Optional encryption to get it working Anyone resolve this? It smells like an IOS bug, but we're using latest MD

Hi all, We've purchased 3 Cisco 887VW (VDSL over PoTS) and have been advised they can be used as ADSL2+ routers I've configured many 887 and 877 routers before for DSL, but never VDSL. We've followed the documentation at http://www.cisco.com/en/US/docs/routers/access/800/880/software/configuration/guide/880_basic_router_config.html#wp1174524 but the problem is there is no ATM interface showing up in config, nor can one be configured controller VDSL0 operating-mode can only be set to Auto also Troubleshooting so far: Connected to ADSL2+ line in the hope that it sees the ADSL2+ connection and creates an ATM interface Upgraded IOS image to c880data-universalk9-mz.152-2.T1.bin Upgraded VDSL chipset firmware to 120330_1738-4.02L.03.A2pv6C035j0.d23j I was beginning to think the unit was faulty, however opening a second 887VW confirmed that there was still no ATM interface I'm sure at this point it's that the method for configuring has changed, there is an Ethernet seperate from the switchport but I'm not sure how this would be achieved As for the interfaces, the back of the unit has the usual 4 FastEthernet ports, a BRI interface and a VDSLoPOTS interface to connect a PSTN line Within IOS, the router sees the following interfaces: BRI0 BRI0:1 BRI0:2 Dialer1 (PPPoE client for DSL) Ethernet0 (Virtual interface, it doesn't exist on the back of the unit, thinking this is where the config needs to happen) FastEthernet 0-3 Vlan1 Wlan-GigabitEthernet0 (embedded AP) wlan-ap0 (embedded AP) Has anyone come across this before?
