FTP over ATM issue

Hi,
I think it's time to upgrade to a different type of Unix server
No, just kidding.
ATM has the nice feature of rebuilding your packets to transfer to the other site and over there it goes visa versa. A kind of MOdulate DEModulate
It might be that the mtu from your system is conflicting with the size ATM is using, I know you can let this being addapted by your ATM provider. Adapting the MTU size of your packets is addaptable as well (temporarily) using ifconfig. I think it is very wyse to wait to get some more (different) answers from multiple people as this does not looks to be an easy problem. If nothin else comes out I'dd defintly try to get in contact with a specialist from your ATM provider.
Good luck.

ng_atmllc
NG_ATMLLC(4) BSD Kernel Interfaces Manual NG_ATMLLC(4) NAME
ng_atmllc -- ATM LLC netgraph node type SYNOPSIS
#include <netgraph/ng_atmllc.h> DESCRIPTION
The atmllc node type translates frames in to and out of ATM LLC encapsulation, as specified by RFC 1483. In LLC encapsulation the protocol of a given protocol data unit (PDU) is specified by an IEEE 802.2 LLC header, possibly followed by an IEEE 802.1a SubNetwork Attachment Point (SNAP) header. This node currently handles the Ethernet and FDDI protocols. The node transmits and receives ATM PDUs on the atm hook. Received PDUs are decoded and forwarded to the ether or fddi hooks as appropriate. Data received on the ether or fddi hooks are assumed to be full Ethernet or FDDI packets as appropriate and are encapsulated into a PDU and transmitted via the atm hook. HOOKS
This node type supports the following hooks: atm ATM connection. Typically, this hook would be connected to a ng_atm(4) node, which handles transmission of ATM PDUs over an ATM device. ether Ethernet connection. This hook sends and receives Ethernet frames. This would normally be connected to an ng_eiface(4) node if in use. fddi FDDI connection. This hook sends and receives FDDI frames. CONTROL MESSAGES
This node type supports the generic control messages. SHUTDOWN
This node shuts down upon receipt of a NGM_SHUTDOWN control message, or when all hooks have been disconnected. SEE ALSO
