I am trying to setup a static route within 3 routers. I have a CISCO WRT320N, a TENDA AC2100 and a WiFi 5 Dual Band router. I'm trying to keep the largest number of devices connected via Ethernet. I have disabled the WiFi on the CISCO and the TENDA routers, so the WiFi router can handle that task. There is also the router provided by my ISP as it is shown below.
The reason I am not connecting my devices using just a switch directly to my ISP router is because I was having a very low performance, so my ISP sent an "expert" to fix the problem. After trying with different options, he realized the problem was with the DNS, so I have to manually change the DNS on every device to 8.8.8.8, 8.8.4.4 (which I think is the Google DNS). Since it is not possible for me to setup my ISP router, I decided to use my own routers and setup the DNS to 8.8.8.8 and 8.8.4.4, now every device gets the correct DNS using DHCP (better than setting a static IP to almost every device on my house). Since I need communication between every LAN devices, I am setting up a static route as it is shown below:
- WRT320N:
- LAN Network: 192.168.3.0/24 Gateway: 192.168.2.2 Interface: LAN
- LAN Network: 192.168.1.0/24 Gateway: 192.168.0.100 Interface: WAN
- WiFi Router:
- LAN Network: 192.168.2.0/24 Gateway: 192.168.2.1 Interface: WAN
- LAN Network: 192.168.1.0/24 Gateway: 192.168.2.1 Interface: WAN
- Tenda:
- LAN Network: 192.168.2.0/24 Gateway: 192.168.0.101 Interface: WAN
- LAN Network: 192.168.3.0/24 Gateway: 192.18.0.101 Interface: WAN
I used CISCO Packet Tracer to simulate the static route and I can send ICMP packages between all devices on every LAN without any problem. However, on my house there is only connection between the LAN2 to the LAN3 (and vice versa), but the LAN1 does not seem to be communicating at all either with the LAN2 or LAN3.
I have double checked that the static routing is the same as the one I configured on CISCO Packet Tracer, so I am not sure if I need to do any extra configuration on my routers of if I am doing something wrong.
I am a newbie so if someone knows a better way of doing this I would appreciate it.
LAN Network: 192.168.2.0/24 Gateway: 192.168.2.1 Interface: WAN
is wrong (well, inappropriate, but it still sort of works) since192.168.2.0/24
should be a direct route (i.e. no gateway). And you should not need to add such route manually.
