Hi all,

I have a network question.

On a Local Area Network, I have 2 OPIs 
(OPI1 & OPI2 : SUNs with solaris 2.6 and R3.13.0.beta11). 

OPI1 has 2 ethernet interfaces :
-the 1st on LAN (le0).
-I define a subnet on the 2nd (le1) using C adressing 
where I put 2 IOCs (MVME162 with vxWorks 5.2).

So far, I run CA-client applications using only OPI1 
to reach the PVs on IOCs. Now I need to reach them with
OPI2, so I made the following changes :
-OPI1 is declared as router.
-on OPI2, I add route to access subnet of OPI1
(route -n add ...)
-routeAdd ... on IOCs.

I can ping and telnet the IOCs from OPI2 but CA-client 
applications (MEDM,...) are unable to connect the PVs.

I also have in my resource.def :
EPICS_CA_ADDR_LIST=x.x.x.x   (#IP OPI2)
EPICS_CA_AUTO_ADDR_LIST=YES

"casr" on IOCs says only OPI1 is client.

Could someone tell me what I am missing?
thanks,
