X.25 requirements

Using the OFTP V1 over X.25 or over X.25 over ISDN requires a router to bridge the TCP and X.25 networks. Both transports have been tested with Funkwerk router models R4300 and X8500.

X.25 firewall requirements

The following table lists required firewall exceptions for X.25.

Description

Source

Destination

Control connection

All Activator hosts, random port.

All routers, TCP port 146.

Monitoring connection

All Activator hosts, random port.

All routers, UDP port 161 (unless changed).

Inbound data connection

All routers.

All trading engine hosts, one port per embedded server using X.25.

ISDN firewall requirements

All instances of Activator must be able to connect to every ISDN router on its remote CAPI port (2662 by default). No reverse or call-back connection is made, as with X.25.

For the CAPI service connection for X.25 over ISDN:

  • Source – All Activator hosts, random port
  • Destination – All ISDN routers, TCP port 2662 (unless changed)
