Hi,
I configured our new business router to forward all FTP traffic to our local FTP server using IPv4 Firewall Rules under Firewall -> Access Control.
It's setup like this:
When we run a ping to google.com, the usual ping is around 30-50ms. Whenever we start a download from our FTP server, the ping almost immediately increases to 500+ ms and as soon as we stop the transfer it drops back down right away. The transfer speed is around 250 kB/s, which is what it always was.
Any help would be greatly appreciated.
