Sadly the fix is as you suspect. While one could ask why VPN for a home network, I'll share I rejected VPN for home and opted for OpenSSH connections instead.
I am trying to install VPN software from work, but it won?t run with my VPN software for my home. Both work independently. When I install the VPN software from work (Cisco), it removes my VPN software (Netgear)from my home network . If I install the Netgear software after the Cisco, neither one works. Is there any way to keep programs separate with XP (in separate user accounts), other then a separate petition and a separate OS?
