no internet access on Ethernet ports

Hello all,

for a function test i need to get internet connection with a IR 829. before i worked allready with a 809 and used the setup on that 829...unfortunately not successful. I modified it here and there a bit now i am able to ping 8.8.8.8 via console port. but not over GE 1 to 4. on a connected computer i get an IP address from the dhcp pool i can also ping the 829 from a connected computer but i can not ping 8.8.8.8 and i have also no DNS.

The actual config looks as follows :

~=~=~=~=~=~=~=~=~=~=~= PuTTY log 2020.04.08 09:04:27 =~=~=~=~=~=~=~=~=~=~=~=

Make these changes - 

 

1) In your DHCP pool setup - 

 

dns-server 8.8.8.8  + any others you want to add 

 

2) Your NAT access-list - 

 

permit ip 192.168.7.0 0.0.0.255 any

Thanks a lot Jon. It seem to be fine now.

Hello

Your nat access-list isn’t correct and you have multiple default routes pointing towards various egress interfaces

Suggest you change this and test again.


no ip route 0.0.0.0 0.0.0.0 Vlan1
no ip route 8.8.8.8 255.255.255.255 Cellular0/0
no ip route 0.0.0.0 0.0.0.0 Vlan1 dhcp
no ip access-list extended NAT


ip access-list extended NAT
permit ip 192.168.7.0 0.0.0.255 any
