    I have purchased a Cisco 877W as a Draytek replacement and I am having problems.

    I have configured it to connect to my PPPoA ISP OK and the network test in SDM reports that the connection is OK. (only after inserting the DNS servers hidden away in additional tasks).

    The default route is setup and VLANs configured.

    I can ping my WAN IP but get 25% on the ISP gateway address. I think the default MTU for Cisco is 1400 which is a little low. I don’t think that is the problem.

    Here is my running config. ((the firewal stuff has been removed due to size restrictions))

    I would appreciate any help with this problem.
