Firewall and company VPN

[9ck]

Hi forum
I've setup firewall rules to reject/block connections to the RFC1918 range, but my wife and I often work from home and use a secure VPN connection to log into our company networks. It's working right now, but I see a lot of rejected request because the source (company PC) is trying to reach a destination within the RFC1918 range. What would best practice be in this situation. Separate VLAN with no rules blocking the RFC1918 range?
