40 Domain Name Not Working Router Update

The problem i have encountered is the router is capable of pinging ip addresses but is unable to ping domain names.
Domain name not working router. I can provide the relevant configuration info if there isn t something obvious i m missing. Recently i have changed my router and configured all virtual servers with proper port forwarding. The router is not resolving domain names.
The router manages a few ubuntu servers with v16 04 x y z etc. Hi i have a cisco 2621 router and i have a few issues. Furthermore i am unable to access internet resources from my workstation that is directly connected to the router.
We have a client with quite strict security policy. Could you let me know what i need to do to resolve these two issues. I am unable to ping any public ip address from within the router 2.
From my computer at my home i can log into client s vpn and then access the router with ssh command like ssh admin 12 34 56 78. I am currently setting up a uc540 that i bought used that does not have a configuration.
