DDWRT synology nas no longer works

Question

I recently upgraded to DDWRT on my router, After doing so, I can't login to my Synology DS213's web interface (says cannot login as this account, root admin and my other admin account dont work) Also, the ssh keys I had setup that worked fine, no longer work. I get

    ssh -vvv root@192.168.1.115
    OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007
    debug1: Reading configuration data /c/Users/chs/.ssh/config
    debug2: ssh_connect: needpriv 0
    debug1: Connecting to 192.168.1.115 [192.168.1.115] port 22.
    debug1: Connection established.
    debug1: identity file /c/Users/chs/.ssh/identity type -1
    debug1: identity file /c/Users/chs/.ssh/id_rsa type -1
    debug1: identity file /c/Users/chs/.ssh/id_dsa type -1
    ssh_exchange_identification: Connection closed by remote host

And I cannot getinto the web interface to enable Telnet to even get in to check my config files. Any ideas?

Solved, my Synology NAS local IP changed from .115 to .135, also I needed to enable DDNS on DDWRT. After doing so I was again able to SSH into my NAS with pubkey authentication as was already setup.
