Hi,
We have an ATM ds3 connection from our premises in the south of England
all the way to London. At each end we have two FreeBSD machines with
Fore 200E ATM cards. Since the cards are 155 Mbit, we employ the use of
two Metrodata ATM 5300 SW DSU devices, which should convert the data
rate from 155 Mbit to 45 Mbit and vice versa in reverse. The problem is
that after everything is supposedly configured, when I send some data
down the link to the other end(i.e. A PING), sure enough it appears at
the other end, but only as an input error on the interface.
Here is some data about the configuration we are using.

The machines have been running on FreeBSD 4.2/4.3 but are both now on
3.5.1 and our aim it to setup one PVC between the two computers enabling
us to route our ip traffic between the two locations. We have enabled
flow control so as not to overload the ds3 link, and have tried various
different configurations.
Also commands we used to initiate the PVC are:
atm set netif hfa0 fa 1
atm attach hfa0 sigpvc
atm add pvc hfa0 0 126 aal5 snap ip fa0 <remote end IP>
I have basicly read through any infomation I have been able to find on
the subject, including the FreeBSD web site, and I get the impression
that this is a setup that should work.
If anyone knows of anything we might be doing wrong, help would be
gladly appreciated.
Regards
Ben Wilkinson
