We have one Cisco ASA5510 firewall and we terminated 50Mbps leased line into that firewall.
We tested the Internet line by directly connecting to my laptop, got 49Mbps download speed and 40Mbps upload speed.
After that we connected my laptop to firewall interface, we are getting download speed 49 Mbps but whereas the upload speed is dropping to 4 Mbps. we tested many times but the issue remains same.
Let me know where is the issue? Is there any minor configurationrequired on the firewall?
