Hello,
I am trying to solve an issue, but no luck so far. I hope you can help me.
I have a RUTX11 device (RUTX_R_00.02.04.3 firmware) where I created different networks for LAN1 (192.168.24.0/24), LAN3 (192.168.25.0/24) port and for a separate one for Wireless (192.168.26.0/24) as well. I reach the internet via mobile. Everything works fine, I can reach the internet from every network (LAN1, LAN3, WIFI). I can also reach computers from one network to others in a different network, all good.
I need to integrate the above to an old network (192.168.22.0/24) using RUTX11 LAN2. The old network has separate DHCP and internet and can't use RUTX11 for internet, but still need to reach the computers connected to RUTX11.
I have these settings for LAN2 (IP 192.168.22.22)
VLAN
LAN2 - Page1
LAN2 - Page2
I can ping any device from a computer in the old network (192.168.22.0/24) through RUTX11 LAN2 to LAN1, LAN3 or WIFI. Of course, I had to add routes in the gateway of 192.168.22.0/24 where set the next hop to the LAN2 IP (192.168.22.22) if the destination is 192.168.24.0/24 or 192.168.25.0/24 or 192.168.26.0/24).
The issue is that I can't ping any computer in the old network (192.168.22.0/24) from a computer connected either LAN1, LAN3 or WIFI in RUTX11. Interestingly, if I SSH to the RUTX11, I can ping any computer from there in the old network (192.168.22.0/24). So, from the RUTX11 itself it's ok, but not from any computer connected to RUTX11.
In short
- Traffic works from old network (192.168.22.0/24) -> RUTX11 LAN1, LAN3, WIFI
- Traffic doesn't work RUTX11 LAN1, LAN3, WIFI -> old network (192.168.22.0/24), only from the RUTX11 itself if I SSH to it.
In desperation I created the following firewall zones as well. Still no luck.
After that I added the below traffic rules. Still no luck.
Output of "route -n" after SSH into RUTX11
Why can I ping everything in the old network if is SSH to RUTX11, but not from a computer connected to LAN1, LAN3 or WIFI port of the RUTX11?
How can I fix this?
Thank you.
