I'm wondering what I think may be the same thing. Is it possible to tunnel EPICS over TCP? I'd like it to work between subnets without having to dual-home a host on both.

Thanks,
Ryan

Hi, all,

My network’s topology is like this:

              router A                          router B
           +-------------+                   +-------------+
           | 202.201.1.4 |                   | 202.201.1.5 |
           +-------------+                   +-------------+
             /                                \
            /                                  \
           /                                    \
       +---------------+                     +---------------+
       | 192.168.1.200 |                     | 192.168.1.100 |
       |   CAS         |                     |   camonitor   |
       |               |                     |               |
       +---------------+                     +---------------+

Could it possible to get pv from another subnet?

Could it possible to Set the CAS’s EPICS_CA_ADDR_LIST to 202.201.1.5,
and then configure router B, map the port 5065 to 192.168.1.255:5065?

or I have to replan the whole net and use layer 3 switch to
connect the subset?

                    +------------------------------+
                    |    layer 3 switch            |
                    +------------------------------+
                     /                         \
                    /                           \
                   /                             \
       +---------------+                     +---------------+
       | 192.168.1.200 |                     | 192.168.2.100 |
       |   CAS         |                     |   camonitor   |
       |               |                     |               |
       +---------------+                     +---------------+

Thanks for reading.
