Network and Vlan no internet

Hello Everyone!

Merry Christmas  !!!

This will be my first post here and I bit exacted . I am kind of beginner in Cisco networking. I am trying to build something as Soho network. I have a problem with topology  and I can not find where is my wrong.

I can not connect my V LAN 's to internet, but most of the host communicated together

I would like to apologies if my questions is too stupid but i need to know where is my wrong

 

Thank you in advance!

Cisco 2651 and switch 2950 24

 

You can see the configuration of my network here-

Hello.

I have one more 2651 router and I can try him with brand new config.
What do you think?1!?

Thank you for your help for all of you!!! 

@MarkoAnastasov45813 Hello again..

 

Please, make changes below;

 

no ip route 0.0.0.0 0.0.0.0 192.168.0.1 254

no access-list 1

 

ip route 0.0.0.0 0.0.0.0 192.168.0.1

access-list 1 permit 172.16.1.0 0.0.0.255

access-list 1 permit 192.168.10.0 0.0.0.255

access-list 1 permit 192.168.20.0 0.0.0.255

 

which device is 192.168.0.1? It your switch? or your Modem?

 

You will need create three routes back to your router on this device to your VLAN's.

 

Log on this device 192.168.0.1 and create three routes, like below;

 

ip route 172.16.1.0 255.255.255.0 192.168.0.49

ip route 192.168.10.0 255.255.255.0 192.168.0.49

ip route 192.168.20.0 255.255.255.0 192.168.0.49

 

 

I think that you didnt my suggestion, try again.

Hello Jaderson. Thank you so much for your help. 

I unrestrained what do you mean but my home router does not give me opportunity to do it. It is very simply and not much manageable unfortunately. I will try to find other way to do it. Probably I will connect my to 2651 router together and after that I will try to play with next hop and also I will put L3 switch 3650 .

This is my first CCNA lab and probably need time to be set up, but I am sure to be ready soon.

Thank you very much for your help and help from Paul and Georg!!!

Hello Georg!
