after making ip tcp adjust-mss 1360 

i still cannot access internal websites

[balaji.bandi]

You are not able to access internal website from external ?

you do not have any port-forward or static NAT entry here to serve the request,

what is the website IP address here ?

[alexandercircuits83036]

I am a newbie and was trying to figure out why i cannot access to the internet

I am a little confused as to the exact setting for updating the Route setting

i entered:

:# ip route 0.0.0.0 0.0.0.0 192.168.1.1

but this was fruitless

Any assistance here would be welcomed

The Router config file is above.

I am not that fluent as to how to achieve this using the Route command.

Thank you.

Who has advised this MTU ( Service provider) - before we tweak MTU, let's try the below config - BOLD was the change suggested.

Test and advise.

i have the same issue.Even after implementing 'ip tcp adjust-mss 1360' on my network, accessing internal websites remains a challenge on my setup, as observed on my website, eyebrowsbar.
