After IP address change my server cannot work correctly

Yesterday I changed server IP address. I set wrong IP interface a Volker helped me to solve.

But today server run just in local network and cannot connect host outside LAN.

 

 

See this:

 

$ tcpip sh inter

Re: After IP address change my server cannot work correctly

Antonio,

 

you don't have a default gateway defined, where packets should be sent to, whose destination is outside your local IP network 192.168.13.0.

 

TCPIP SET ROUTE /DEFAULT/GATE=192.168.13.1 [/PERMANENT]       ! if that is your local routers IP address

 

That route will then show up as destination 0.0.0.0 in TCPIP SHOW ROUTE

Re: After IP address change my server cannot work correctly

Antonio,

 

is your default gateway defined ?

 

$ TCPIP show route /def

 

If it isn't defined, then :

 

$ tcpip set route /def/gat=xx.xx.xx.xx/perm

 

where xx.xx.xx.xx is your default gateway ip address.

Gateway is defined in permanet DB but there is no trace in current configuration.

 

$  sh hos dns1

     LOCAL database

Host address    Host name

192.168.13.1    DNS1, gw

 

 

 

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
$ sh rout /perm

Re: After IP address change my server cannot work correctly

Antonio,

 

you need to use the /DEFAULT qualifier when specifying a default gateway:

 

$ TCPIP SET ROUTE/DEFAULT/GATE=dns1 [/PERM]

With /def works!

 

Thanks
