    Hi there,

    I just bought a Cisco-Linksys router E2500.
    Installation went fine, Internet is ok...

    Just a small issue when I'm trying to upload a file to a distant FTP server.
    Any file < 1KB is fine but when the file is larger than 1KB, I can't upload it anymore (it just doesn't complete the upload).

    I tried passive/active mode for my FTP connexion.
    I tried port forwarding.
    Now I deactivated the router firewall and I put myself in the DMZ.
    I also tried to upgrade the router's firmware to the latest official version, and to the DD-WRT latest version.

    But still I can't upload files larger than 1KB. With my previous router, it was working pretty fine.

    The ultimate test was to connect myself on a VPN server and try to upload the file to the FTP through the VPN server. And it worked!!!

    But I don't want to be always connected to a VPN when I want to transfer files to my FTP server...

    Does anyone here have an idea about how to solve this issue?

    Many Thanks for your help!

    Found the solution: changed the MTU size to 1365.
