Description

When modifying an existing static route, e.g. changing subnet to be routed, the modified route is added to the current routing table instead of replacing the existing route. To get the correct routing table, you have to reboot pfSense.

Example:
Have an existing static route "Destination = 10.0.0.0/8, Gateway = 10.100.0.1, Flags = UGS, netif = hn0", then modify the Destination to 10.0.0.0/24 by GUI "System/Routing/Static Routes", and you will find two entries in routing table (on GUI "Diagnostics/Routes" or on shell "netstat -rn"): The original one and a new one "Destination = 10.0.0.0/24, Gateway = 10.100.0.1, Flags = UGS, netif = hn0".

Tested this on 22.01.a.20211108.0600.
  • Deleting a static route does not prompt for an "Apply Changes" confirmation.
  • Deleting a static route entry does not remove it from the route table.
  • Removing an entry from a network IP alias being used in a static route entry does not remove it from the route table.
  • Changing an entry from a network IP alias being used in a static route entry adds the new route but does not delete the old one.

after modifying it to be 192.0.0.0/8 the new route is added to routing table and old one has not been removed .

192.0.0.0/8 10.100.100.1 UGS 0 1500 em1
