After IP address change my server cannot work correctly

AntonioMariaV — Tue, 08 Oct 2013 06:45:48 GMT

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

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

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.

Antonio,

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

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

With /def works!

Thanks
