Rules not respected 2?

[pfpv]

I see there is a similar topic but my situation is different, so I decided to create a new thread. I am on 2.5.2.

I am on multiWAN with failover. DHCP cable modem is primary WAN1 and DSL with PPPoE is backup WAN2. I have a gateway group where they are Tier 1 and 2 respectively. But this likely doesn't matter. At one point there was a cable network problem in the area (high ping, packet loss), so I excluded the primary WAN1 from the gateway group and left only WAN2, so the home network was on WAN2. I wanted to monitor the situation with WAN1 and created a LAN rule for one PC only and placed it on WAN1 gateway, not the group. I ran ping plotter on the PC pinging the CMTS, so it was just one hop.

It was working for several days but one day I looked at the ping plotter and saw that pings were going over multiple hops, sure the traffic went through the gateway group which had active WAN2 (DSL) instead of WAN1 that was defined in the rule. I went to edit the rule and clicked Save without changing anything. Applied, and pings went through the proper gateway (WAN1) again.

I have to say that I have schedules, and cron reloads filters every 15 min. Maybe that rule was dropped at one of such reloads but it was active in the GUI when I went to "edit" and save it. I was quite surprised when it happened but it didn't happen again. I stopped using that rule after a while.
