Router Configuration
-
I'm going to have to say that from your explanation, you have something wrong with routing.
The only place you need to have nat running is between your modem and your netgear router. You do not need to have nat running between your internal switch or router and the netgear router again.
I believe you have your default gateway set improperly too. The next hop ip address should be internal ip address of the netgear router. I cannot tell by your snippets you're showing me what the topology of your network is like.
So please post what is connected to what...
for example: Internet to modem to netgear to router to switch ? or is it a different order
-
I don't have pictures, but Should it be
Soho router Netgear to Cisco router "int G 0/0"
Cisco Router to Cisco Switch "int G0/1"
Switch to PC "int 16 vlan 20"I haven't configure DNS yet because in Vlan 10 I will be configuring the servers
-
from the router ping your Netgear router: should be good
from the switch ping the ip address your cisco router on g0/0: should be good
from the router show routing table and verify you see all the networks you've created. and verify you can ping a host in each vlan you created.
for each of your hosts, do they have the default gateway of the vlan you've put them into? if so you should be able to ping those default gateways of each host.
On your router, when you create a default route. it should point to the internal ip address of your netgear soho router.

Ronnie I do appreciate your time and effort. But I don't understand how to achieve my goal. I want to try to explained and hopefully you can tell me what I'm missing.
I want to have 3 different Vlans
Vlan 10 Servers and Network equipment 192.168.1.1
Vlan 20 Workstations (using Windows HyperV) 192.168.2.1
Vlan 69 management (to manage Router and Switch) From That Network 192.168.69.1
Vlan 777 Native
Trunk fa4/0/24Vlan config
Router config
Until then everything good.
Routing table

What I want to achieve is When I connect my server to Vlan 10 in the interface 4/0/11 (example) My Server can go to the internet and update. When I plugg a workstation to Vlan 20 int 4/0/19. Can Go to the internet. What else I need to configure in the router to make it happen?

If you cannot do the steps that I listed above:
from the router ping your Netgear router: should be good from the switch ping the ip address your cisco router on g0/0: should be good from the router show routing table and verify you see all the networks you've created. and verify you can ping a host in each vlan you created. for each of your hosts, do they have the default gateway of the vlan you've put them into? if so you should be able to ping those default gateways of each host. On your router, when you create a default route. it should point to the internal ip address of your netgear soho router.
You cannot accomplish this. You have to set this up step by step if you do not understand. First get your router to connect to the outside world. Second, get each of the vlans to connect to your router and have routes that will ping the router's interface connecting to netgear router. If you cannot get the switch to talk to the router, you will not accomplish the rest.

The host 192.168.2.10
can ping the router both interfaces 192.168.2.1 and 192.168.0.253 (the netgearside)
But Router can't ping host 192.168.2.10 unless I turn off firewall then router can ping it.Any suggestions?
-
Nervermind, I turn on network discovery. Now I can ping the host.
-
Would double Natting (Nat) be the reason why my hosts can't access the internet?
-
@Victor-Rosa-Serrano,
You're already doing double nat. from your netgear, then the ISP. -
I'm able to ping the hosts in each vlan, and their gateways. They all are able to ping the interface connected to the netgear, Still the Router doesn't allow dns traffic trough. I created a DNS server in 192.168.1.2. How can I point dns & DHCP traffic to that server. In the video you configure the router as a DHCP and DNS server.
-
Host Vlan 10 WinSvr2016 (device ip 192.168.1.2)
It pings both sides of the Cisco Router.
Cisco Router pings the server 192.168.1.2 in Vlan 10
But still no internet connectivity. What I'm missing to configure in the router so this server has internet access?
Here is the IP route
-
Can the router ping out to internet?
What is the default gateway of your server?
-
If you look in my routing table, 192.168.1.1 / 24 or any other can't reach 192.168.0.1 because they don't have a route there. My Netgear router is not manageable. So I resolve the issue implementing Dynamic Nat. So I treat 192.168.0.0 /24network as outside network (in theory it is) So by using Nat It got resolve. Thanks for all the information you provided for me. Now it resolve. My next project will be configure a relay agent that could talk to my DHCP & DNS server in Vlan 10 that could serve vlan 10 and 20 as well.

Glad you figured it out.
