We have a Cisco Linksys RVS 4000 VPN router. The previous contrator company configured it and didn't leave any documentation to us. I tried to log into this router with default username and password. Both are admin. It failed. Tried some other combination. Failed either. I know I can push the reset button to back to factory setting. But they configured some VPN already. I want to try login first before I go to factory setting. Is there any other way to recover the password for this model?
Thanks a lot for the help.
