routing between two LANs - pings are one-way

[rocra]

A newbie here, setting up my first router with four NICs.

Problem: pings between two local lans are flowing fine from LAN -> OPT1, but NOT from OPT1->LAN

Setup
OPT1 is named NAS

Interfaces:
igc0 WAN
igc1 LAN       192.168.2.1/24
igc2 OPT1(NAS) 192.168.3.1/24
Both LASs enabled
"Block private networks" unchecked on both

Firewall Rules:
in IPv4   *   LAN net   *   *   *   *   *      Default allow LAN to any rule
in IPv4+6 *   NAS net   *   *   *   *   *      Default allow NAS to any rule

DHCP enabled on both interfaces

Tests:
Ping

• From 192.168.2.50 on LAN: ping   ok to 192.168.3.1 and 192.168.3.2
• From 192.168.3.2  on NAS: ping   ok to 192.168.2.1
• From 192.168.3.2  on NAS: 100% loss to 192.168.2.50
• WebUI Ping:   ok to 192.168.2.50
• WebUI Ping:   ok to 192.168.3.2
• WebUI Ping:   ok        source=192.168.3.1 to 192.168.2.1
• WebUI Ping:   100% loss source=192.168.3.1 to 192.168.2.50

WebUI Ping is done using Interfaces: Diagnostics: Ping

Problem solved - it was a firewall setting stopping echo replies to outside local subnet
Resolved by adding 192.168.0.0/16
