Hello,
I have implemented a new firewall but am having problems with my FTP connection. Would someone please review my conf and help me understand where the error lies? FTP is a vital function for the business and I need to rectify it
I am a CCNA student and was assigned this task at work and don't want to fail!
Any and all help is appreciated, THANKS!

Dear Geo,
Try changing the FTP mode from passive to active.
With Regards

I did that and ended up creating an acl of 100 and adding the rules to it, FTP is working now.

hi,
could you add VLAN 2 on your e0/1 trunk?
interface Ethernet0/1
switchport trunk allowed vlan 1,2,9,11

thanks, could you expand on how this helps traffic flow?
