I have Raspi-OpenWRT as the first router from ISP, and Fritzbox4020-OpenWRT as the router behind it (hooked on 192.168.1.0 net). FB's address on the WAN side is 192.168.1.101. I have a Raspi2 (PiOS) hooked on FB in the net 192.168.10.0, and its address is 192.168.10.30.
I am having difficulties in making things on Raspi2 accessible from RP-Openwrt. I am trying in small steps.
First: I want to ping raspi2 from 192.168.1.0 of RP-Opewrt.
On raspi-Openwrt I set:
config route option interface 'lan' option target '192.168.10.0' option netmask '255.255.255.0' option gateway '192.168.1.101'
Note that lan's subnet is 192.168.1.0.
And on FB I set
config rule option name 'ping from wan' list proto 'icmp' option src 'wan' option dest 'lan' option target 'ACCEPT' list dest_ip '192.168.10.30'
And now, my PC is 192.168.1.205 on raspi-openwrt, I type
but it doesn't go through !
I had a similar problem earlier, I got help here, and I thought I understood it, but it seems I'm not quite there;; I am sorry for asking the same question, could you please help;; ??
