I have recently starting using Shrew Soft VPN to connect to my Cisco ASA router. I also use PuTTY to connect to my switches and firewall. My problem is, when I'm connected over VPN I can't ping or telnet into one of my switches and the firewall. I am, however, able to ping and telnet into the other two switches. When I use the same laptop connected directly to the LAN, I have no problems.
