Iam facing delay issue of 10-20 seconds occurs between the time the username is input and a password prompt.

Hello there!


This is very common on any SSH server that is attempting to perform reverse DNS lookup.


So if you are pointing to an internal DNS server, modify your resolv.conf file or similar to add a static entry in for your IP.

Then, it should resolve faster.

I agree with the previous post that the problem is related to SSH and DNS. But if you're talking about a delay when you SSH into the firewall, just try to configure a reachable DNS server under Device -> Setup -> etc...



i will also configure DNS as well as reserve DNS but still not resolve
