Greeting.
I'm newbie on opnsense.
Which is my problem; Routing, NAT, Rules?

opnsense version : 26.1.4

I configured below;
- Interface : Virutal IP 192.168.55.127, master .254, backup .1
- Gateway : Group WAN_GW1, WAN_GW2
- High Availability : Service sync Caddy, Unbound DNS
- Firewall : Destination NAT, Outbound NAT, Reflection for destination NAT, Sticky Connection
- VPN : OpenVPN
- Service : Caddy, Kea DHCP, Unbound DNS, Zabbix Agent

Now I have problem is I can't ping 192.168.55.127 and 192.168.55.254.
And I can't query to Unbound DNS.
But I can ping 1.1.1.1, and use DNS.
And DNAT function are working properly.

How to get icmp reply from opnsense and how to use dns?
On this problem I checked live log, and there is no block.
To avoid NAT, I configured Hybrid outbound NAT and add rule.
Lastly, I adjusted lo0 routing.
All of my effort to solve it, the opnsense doesn't accept me.

Please show me the way to use opnsense properly.
Thanks for your time.

Good days all in all.
