static route works for about 10 mins only

[harj]

I set a static route in pfsense to my home router(192.168.0.0/32). for little while, I can ping the gateway and websites on the internet from a VM attached to pfsense but then it stops working. If I open the static route and save it again, it starts to work again.

I have just started using pfsense so what did I miss? please help me fix this

edit: this is what I see in the packet capture

192.168.1.100 > 8.8.8.8: ICMP echo request, id 1, seq 170, length 40
16:36:29.481811 00:50:56:a5:dc:5e > 00:50:56:a5:4c:a6, ethertype IPv4 (0x0800), length 98: (tos 0x0, ttl 64, id 56705, offset 0, flags [DF], proto ICMP (1), length 84)

I realized that I do not need to add 192.168.0.x since my WAN interface is 192.168.0.1 and /32 was incorrect too. I have removed that. I can see the route in the table but still the ping to google.com or 8.8.8.8 or 192.168.0.1 from a VM(192.168.1.100) connected to pfsense is very random. how can I troubleshoot that?

edit: do I have to reboot each time I save anything? that seems to do the trick
