I'm having a lot of problems with my NAS and my router which I can't find the cause of.
My setup: Synology DS213 with DSM 4.1, Netgear CG3100, two computers running Windows 8 Pro 64-bit
Everything worked fine until one day when the CloudStation-synch-app stopped working on both computers (connection error). I also noticed I can't connect to the NAS-admin-gui with my *.synology.me-address anymore (using IP works) even though the DDNS-service is activated and seem to work according to the NAS. In control panel -> router config of my DS I allready have some port forwards but now I can't remove or add anything with the respons: "Connection failed. Check network settings".
Internet works on all computer and the NAS is connected to internet too.
The only thing I can remember I have done before this happened is to setup NFS for XBMC and also activating SSH and SFTP. But I have tried turning this off again and that did'nt do it.
Any suggestions? I can still access files on the NAS over network and I have internet-access. But it's annoying that I can't get CloudStation to work and I'm also having problem getting VNC to work (don't know if it's related). And I can't access the NAS-gui with my *.synology.me-address with is also annoying. I'd really like to get this working again. Without factory resetting both my router and NAS.
This is what I get when checking logs with "tail /var/log/messages":
When trying to save a port forward change in router config:
Jul 2 22:15:26 routerconf.cgi: lib/crypt.c:50 Failed to open source file.(No such file or directory)
Jul 2 22:15:26 routerconf.cgi: lib/routerdb.c:289 load router desc failed
Jul 2 22:15:26 routerconf.cgi: routerconf.cpp:624 failed to get router description
When trying to "set up router" in router config:
Jul 2 22:16:40 routerconf.cgi: (upnpclient.c:1571) clean up finished
Jul 2 22:16:40 routerconf.cgi: routerconf.cpp:339 init UPnP faild
I don't know if this is messages I got before when it was working as well but I doubt it. When checking crypt.c row 50 it seem to be crypt.h that is not found (?). And according to the last log-error "init UPnP faild" it almost looks like the router hasn't enabled UPnP but I have verified it's activated and I can also see that the NAS has connected with UPnP allright. This is weird. Any help pointing me in the right direction and I will mark it as a solution! I'm desperate!
