Static routes

Lapgoch · 24 Aug 2022 at 17:54

Hi.

Attached is an overview of my network.

In the Asus RT-AC56U router there are 2 static routes defined.

In the TP LInk Archer C2 router there is 1 static route defined.

From PC A i can ping PC B but i cannot ping PC C.

From PC B i can ping PC C.

The firewalls on both routers are disabled.

I need access to PC C from PC A.

Any idea what I am doing wrong?

I'm guessing that the Eagle router does not know how to get to 192.168.0.0/24.

Why so many routers? Just use VLANs, far easier.

Sadly neither of the routers support vlans.
Routers are used to seperate my home network from a plc training network and arduino training network.

Use 1x router.

Trying to learn a bit about networking. Using 1x router wouldn't give the the problems I am having , so I wouldn't learn anything.

You don't learn anything valuable about networking by bodging a load of consumer trash together either. They often will only see a static route as being on the LAN side, and will NAT everything going out the WAN, with no option to change that.

Thanks. It seems I have learned something then.

Asus RT-AC56U should support VLANs, if not it can run OpenWRT or similar that likely will

Can't see anything on the Asus RT-AC56U router that relates to VLANs. Will look into the OpenWRT option. Thanks.

can you do a trcaert from PC C To PC A and see where the packet is dropped

on the TP Link router, what is the next hop for addresses outside of the 192.168.10.0/24 subnet

Will do a tracert asap and let you know. Thanks.

Trace route from pc C shows unreachable.

The eagle router settings are

This is after doing a factory reset. So no firewall settings are applied.
Do i need some extra routes in the eagle setup?

Do you mean use VLAN's. If so my Asus router and TP link router don't have VLAN setup.

Yes you are correct. I mistakenly thought that if I could successfully ping from pc B to pc C that there must be route back.
Could you please advise on what additional routes I need in the eagle router.

Trace route from pc C is better now , but still not pinging.

Can someone tell me if these untrusted and trusted packet filters will allow ping requests through the firewall ?

Thankyou. All is good now.

I'm confused , but yes it's working.
I had tried that route , along with many others but never got ping working and it's still not working.
There is a PLC on the secure side of the Eagle router serving a webpage.
With the route you suggested, configured on the eagle router I can can access the PLC webpage.
Any thoughts on why ping from pc C to pc B never works.
