How do I use the V!CAS as a TCP-X.25 bridge?
The V!CAS can be used as a TCP-X.25 bridge as described in RFC 1086.
Using this mechanism, the V!CAS can be used to allow X.25 and TCP
hosts to communicate by providing an end-to-end ISO-TP0 connection.
Depending on which side initiates the connection (see the examples
under More Info shown on page 129) the V!CAS performs the appropriate
protocol mappings as shown above.
Before you begin
No special information is required to configure the V!CAS as an ISO-TP0
bridge. Please note however that TCP clients must support RFC 1006
which describes how to transmit TP0 packets over TCP.
Configure it
Verify License
Verify your X.25 license. You should see “X.25(ok)” in this menu.
Route for outgoing calls
X.25 routing must be configured so that incoming and outgoing calls
can be established. Using the special local interface (see page 118) a
minimal X.25 rouing setup could be used as follows.
Source Link
local
Destination Link
<X.25 interface name

Use an available X.25 compatible interface name here.
