cisco 1720 and internet-help

[robo99]

Hi, I have subnet network with 1720 router which links to the main lokation where we have ISP connection. In the subnet network I have only few addresses which can access internet.192.168.26.20-30, DG 192.168.26.1 below and above
internet doesn't work, but local network access is perfect.
Please help which setting is responsible for that, I'm new to cisco routers.
thanks

Are the addresses you are using from the private address room? If so, you you need to activate NAT if you haven't done so yet. Can the router access the internet?

 

[robo99]

Yes my router can access internet, because some of the addresses going out. I guess is something with firewall.

I would check the NAT access lists and any firewall settings to see what range of IPs are permitted/denied for either NAT or outbound access.
