It’s very nasty, but there are a lot of options. For example you can give the gateway an address in the link local range and add a route pointing at that. I think that’s the best way. Another option would be to set the subnet mask to /0 and enable ARP proxy on the gateway (that is truly diabolical). Another way is to have a private /30 or /31 as the linknet and then add the /32 public ip as an additional one with a /0 route to the routers ip in the private /30 (and the router can have a /32 route to your ip in the private /30). 1:1 NAT is another option (but that’s not quite the question).
