My isp network is 172.19.59.0/24 and it is a pppoe service, right now i have used over 120 address and the number is growing day by day.
I have an idea of using a router board to open the limits of addresses for future growth by making new networks that can communicate with each others through the router and to get the pppoe service from the original network as well, so the idea should be like this:
Port 1 is for my isp, and the rest are for expansion
Port 2 network is: 172.19.2.0/24
Port 3 network is: 172.19.3.0/24
Port 4 network is: 172.19.4.0/24
Port 5 network is: 172.19.5.0/24
looking forward to get the needed help from you guys by teaching me how to do this please!!
Thank you…
#1 computer (172.19.2.10) is on ether 2, it can ping to 172.19.2.1 (which is the ether 2 IP address). #2 computer (172.19.3.10) is on ether 3, it can ping to 172.19.3.1 (which is the ether 3 IP address).
The two computers can not ping to each other.
Unfortunately there are many unknowns in this case. You have provided little relevant information.
The router will route your traffic by default. There are many reasons that the traffic might not reach its destination. There are several reasons your computers wouldn’t respond to ping.
I’d venture to say that most people here are willing to provide educational replies to simple questions, but most won’t do your work for you for free. With that in mind, I’d suggest looking at the router firewall config, router logs, your computer firewall logs, and performing packet captures on router interfaces and the computers to see where the pings are being seen and where they are not. That should lead you to your solution.
Okay, so far the code below is doing what i need except for the pppoe connection, as for the connection between the three networks on ether2, 3 & 4, i can ping and communicate any pc to another one from the other networks, so the only problem for now is the pppoe that is not working:
And what exactly doesn’t work? If devices in those 192.168.x.x on ether2-4 use .1 (the router) as gateway and can communicate with each other, then they must also be able to connect to anything else the router itself is able to connect to. That’s what the masquerade does, anything going out via ether1 will use 172.19.59.253 as source address.
While i’m waiting for new thoughts from you guys to help me out with my case, i managed to setup DHCP servers for the networks, it worked and i can ping from any to any network but still can not make any PPPOE connections at all.
So this is my new setup with the DHCP servers
I don’t know what exactly you edited in original post, but now it sounds as if you want to have devices connected to ether2-5 act as independent PPPoE clients and be able to connect to ISP’s PPPoE server? I’m far from being PPPoE expert, but I don’t think it’s routable. And if I’m not completely missing the point (that’s entirely possible), I don’t really understand what you’re trying to do, why would you need a router at all if it would not be actually routing anything? And if ether1 goes to ISP, why does it have IP address at all, shouldn’t there be PPPoE client on other1? Yep, I probably don’t understand your requirements at all.
I’m all open to your suggestions, what i have edited in my original post is the “class c” sentence which i have removed from the post.
Let me rearrange for you:
1- I have a main switch that is connected to my ISP.
2- I have branch switches connected to the main switch.
3- I have computers connected to the branch switches.
4- My IP range is 172.19.59.0/24, so these are 254 address.
5- I have used over 120 address so far (I will run out of IPs soon).
6- My internet connection is PPPOE service.
7- The computers should be able to communicate between them in order to access shared folders, servers and printers.
That’s it!!
So basically, i wanted to creat new networks for future growth, these networks should be able to communicate between each others if possible, and the clients should be able to establish PPPOE connection on their computers.
