Server cannnot connect after IP addrress change

I have an old rx2620 with OpenVMS V8.4.

In order to test some software i have to create a VPN with another site. Both sites have same network 192.168.1.0, so I had to change my local network.

I tried to change via @TCPIP$CONFIGURE, core, interface but it crashes. So I changed via TCPIP command (set conf interface, etc).

Now server is isolated.

 

Details:

Old IP address (WE0) = 192.168.1.13  New IP Address 192.168.13.62

Old IP address (IE0) = 192.168.1.134 New IP Address 192.168.13.61

 

I cannot set route

TCPIP SET ROUTE 192.168.13.0 /GATEW=192.168.13.1

%TCPIP-E-ROUTEERROR, error accessing routes database (TCPIP$ROUTE)
-SYSTEM-F-UNREACHABLE, remote node is not currently reachable

 

Ping to ateway does not work

PING 192.168.13.1

ping: sendto: no route to host
ping: wrote GW 64 chars, ret=-1


How can I resolve?

 

TIA

Re: Server cannnot connect after IP addrress change

Antonio,

 

shouldn't there be a default route entry ?

 

$ TCPIP SET ROUTE/DEFAULT/GATE=193.168.13.1 [/PERMANENT]

 

assuming 193.168.13.1 is your router/gateway address for this network ?

Re: Server cannnot connect after IP addrress change

This happens when I try to set a route

 

$ tcpip

set rout 192.168.13.0 /gateway=GW
%TCPIP-E-ROUTEERROR, error accessing routes database (TCPIP$ROUTE)
-SYSTEM-F-UNREACHABLE, remote node is not currently reachable
TCPIP> set route /gateway=GW/def
%TCPIP-E-ROUTEERROR, error accessing routes database (TCPIP$ROUTE)
-SYSTEM-F-UNREACHABLE, remote node is not currently reachable
TCPIP>

(note GW is the same of 192.168.13.1)

 

TCPIP> sh host gw

     LOCAL database

Host address    Host name

192.168.13.1    GW, gw

Antonio,

 

> 192.168.13.1    GW, gw

 

You might want to change this to 193.168.13.1 !

 

Or you've got your local IP adresses wrong ?

Re: Server cannnot connect after IP addrress change

Right network is 192.168.13.0

I wrong wrote when inserted host names i64shs and iiashs, so address network and gateway does not match.

 

Tank you Volker
