I have been looking into running a UDP syslog server but would like to limit access to it to only certain IPs, naturally.
Is there a best approach to doing this on fly?
Since fly does not have the equivalent of an AWS security group (at the platform level) would it mean installing something like iptables in my Dockerfile? I have read bits about it which apparently gets complicated when running inside docker with the host having its own rules.
For people that have IP-limited access before with fly, or with a Dockerfile in general, how did you do it?
