If i create an ACL on my border routers to prevent private IPs from coming in, will this have any affect on VPNs? We have several site to site VPN tunnels coming through the router and terminating in an ASA. Just want to make sure

Thanks

It will not, as long as it is an inbound filter on the external interface. The VPN traffic is in tunnel mode so is fully encapsulated. If it gets to and from there over the internet, it will not be blocked by the Martian Filter.
