hi,
on a 3750 catalyst ( Version 12.2(25)SEE2 )
it's not possible to start a FTP from a client in VLAN1 to a server in VLAN2;
is the same client also in VLAN2 than it works fine...
there is no firewall/access list defined...
i get:
ftp> open xxx.xx.xx.xx
connected to xxx.xx.xx.xxx.
connection closed by Remotehost.
ftp>
a telnet and ping xxx.xx.xx.xxx is possible!
any help/idea?
thanks,
martin.

What are you using to route between the VLANs? Are you using the 3750 or an external router?

Martin,
Do you have the command "ip routing" in your config?

So, if u could ping/telnet it between vlan's, routing is fine.
Is there any acl filtering ftp traffic ?

1) the routing is done by the switch itself
2) no i have no "access list"
3) yes, i have the parameter ip routing
here the starting from the config:
....
....
switch 1 provision ws-c3750g-48ts
switch 2 provision ws-c3750g-48ts
switch 3 provision ws-c3750-48ts
ip subnet-zero
ip routing
no ip domain-lookup
!
!
!
!
no file verify auto
!
spanning-tree mode pvst
spanning-tree extend system-id
spanning-tree vlan 1,10-14 priority 24576
!
vlan internal allocation policy ascending
!
interface Port-channel1
switchport mode access
spanning-tree portfast
spanning-tree bpdufilter enable
!
interface Port-channel2
switchport trunk encapsulation dot1q
switchport mode trunk
shutdown
!
interface GigabitEthernet1/0/1

Hi Martin
Are you sure that the problem is with the 3750?
From the FTP information supplied,
ftp> open xxx.xx.xx.xx
connected to xxx.xx.xx.xxx.
connection closed by Remotehost.
ftp>
it appears that you have been connected to the server and that something on the server has then ended the session.
If there was a routing problem on the 3750 I would have expected something like the following,
H:\>ftp
ftp> open 10.10.10.1
> ftp: connect :Connection timed out
ftp>
If the server is a windows based server, is it possible that there is a local firewall (windows firewall) terminating your FTP session?
Best Regards,
Michael
