After upgrading to 2.9.20 Firewall rules "flicker" when using winbox to configure them. Seems to have something todo with the comments, for a half of a second rules are being swapped, if you are in a chain with only 2 rules. If there are more rules on the screen, there is also a random rot...
is it possible to do NAT 1:2 mapping (loadbalancing) with MT?
eg: external IP 10.0.0.10 port 25 is mapped to internal 10.2.0.10:25 and 10.2.0.20:25 (to-addresses afaik only takes a range?)
