Cisco Expert needed 887VA plusnt fibre

[#1]

Hello,

So i wanted to setup a 887va router i had spare (to setup a site to site VPN connection for work)

i can get it connected so the VDSL LIGHT is on and the data light flashes, it even gives the correct external static ip address.
But i cannot access the internet , config below, i would be very grateful!

Try this config, I think it will work. You need to change the *YourUsername* and *YourPassword* to yours.

Connect the phone line to the router using the RJ11 and Ethernet3 to your network.

Try this:

username *-* privilege 15 password 0 *-*

controller VDSL 0

I didn't have much time this morning, so I just posted a full config so that you could compare yours with the one I posted.

First you need to get rid of interface dialer0 as you are using dialer1 for VDSL. You've shut down the atm0 interface which is for ADSL so that looks right.

The Vlan 101 sub interface on Ethernet0 (Which is the VDSL modem) needs a little bit more config to make it work.

You need to add: ip nat outside  to tell the router that its WAN side, also add the following:

ip virtual-reassembly in
no ip route-cache
pppoe enable group global

Vlan1 is the default Vlan for the Ethernet switch built into the router and this looks OK.

Also on dialer1 I think the MTU sizes are incorrect:

ip tcp adjust-mss 1452

ip mtu 1492

@andydis Did the config that Mike suggested work for you? I plan to give it a try later on tonight as I have switched from ADSL to VDSL and want to amend our Cisco router config to suit.

[#5]

@imi Which model of Cisco Router are you using?

The reason I ask is that some of the older 800 series can only cope with about 30 M/bits of throughput with a very light config (i.e. no ip packet inspection). 

Also have you taken a TV package from Plusnet? If so, then the config I posted doesn't support IPTV.
