My router's configuration app (browser-interface) has a page for Virtual Server. It has entries I did not create, at least not intentionally using the interface, for Teredo, Skype, Spotify, uTorrent.
I have two questions about this:
1) how did these entries get there in the first place?
2) I changed the IP address of the gateway from 192.168.1.1 to 192.168.2.1 because we just got FIOS internet in addition to COMCAST, intending to phase out the COMCAST in the very near future; the FIOS router was defaulted to 192.168.1.1 so I changed my router's IP address to ...2.1 and now some though not all of these entries for Teredo, Skype, Spotify, and uTorrent still show the 192.168.1.x IP address. Can these "stale" addresses be deleted?
