Can't ping device on optional network Watchguard Xtm 5Series

I'm trying to ping a router on the optional port and can't get a responds thru the trusted network. I have another router on that optional network that responds to ping. To test I've plug in a computer directly into the optional network, assigned an IP and i'm able to ping both routers. But from my trusted network, I can only ping one router .

The trusted network is 10.0.1.X/24 (Interface
the optional network is 10.0.2.x/24 (Interface

Router A is (can ping from trusted)
Router B is (CANT ping from trusted)

Test computer1 plugged directly into same hub has above routers. I can ping both routers

Test computer2 plugged into same hub has trusted network. This computer can only ping Router A.

There is nothing showing up as being blocked in traffic monitor.

How can I tell if IP is being NAT to when it crossed over to the Optional network? Router B MIGHT have an access rule only allow traffic from 10.0.2.X network....But I can't verify that. Do you know if the 10.0.1.X is NAT to 10.0.2.X when It crosses to the optional port?

Why is it being blocked with no log?

Thanks for any help in advance.

it ended up being one of the routers had an access list not allowing my internal ip's

setup a rule for icmp from trusted to optional

thanks for the reply but I've already have a rule for icmp that says allow from 10.0.1.x to any. (which is trusted to any).

any other suggestions?

I did notice I can ping the device from the diag tool in system manager.

also the router does have an access rule that only allows 10.0.2.x ip's.

Like I mentioned on my first post, if I setup a computer and plug it directly into the optional network 10.0.2.x...I can ping the router.

Also can ping router from the diag tool in system manager on the watchguard firewall.

but not from the 10.0.1.x , there is nothing showing up as being denied.

do you have any routes setup?

I have a xtm 515 with 4 remote offices and VPN setup.

I do not have any ip addresses in the from and to for ping.  I have any trusted and any optional in from area and any trusted and any otional in the to area with no issues.

In the ping setup

My answer I believe was used to make person think about other devices and if the ports were open for access.

issue was related to an internal setup
