    This is a very useful and much appreciated collection, however, you don’t seem to have a copy of the firmware version 0.0.026.
    I think I have now read the entire Internet in search of this illusive version. It’s spoken about all over the place but no one can provide a download link anywhere, or not that I have seen. (My CCO account doesn’t doesn’t have access to the download)
    On the off chance, I don’t suppose you have a copy, or are able to obtain a copy on my behalf ?

    I have a Cisco 871W that currently has C870-ADVSECURITYK9-M, version 12.4(4)T8… should c870-advsecurityk9-mz.151-4.M10.bin work for this router? If not, do you have something new(ish) that would?

    I have a Cisco 877 Router Adv Security K9..NO additonal VLAn Supported.
    So i tried to del the Flash and uploaded ADVANCE IP Services. I tried all IOS and in some IOS the Dialer services does not come up some come up but IPSEC VPN comes and goes off.NO LUCK.

    I downloaded the Advance Ip Services for Cisco 877 c870-advipservicesk9-mz.124-24.T1.bin.It worked for me for creating Additional VLANS as it wasnt available on
    existing IOS Adv Security.
    Thanks for the good work. Please also upload other routers IOS and ASA.
