Upgraded to 5.1L and lost Internet connectivity???

[BobMCT]

System: RS6K F50

Prior to upgrading I saved all the necessary networking conf files. Then I performed a 'clone' update from a mksysb tape made on a master machine. Upon completion I restored the backed up files. I then used smit tcpip, further config, to verify and/or set the appropriate controls/routes, etc.

I can ping anyone within the network and even ping the cisco router but cannot connect outside of the network. Likewise coming in.

I've used netstat -rn to verify the routes, flushed the routing table, rebuilt it and still cannot get outside.

Any ideas, clues, suggestions, etc? Please help.

You may have to set up the minimum configuration information in the odm
again by removing the information and setting it up again...

Run netstat -in and see what is up or shown as there any asterics?
Then do an ifconfig statement for each en or et

ifconfig en0 down ( or et0 if using the other 802.3 network setup)
ifconfig en0 detach
ifconfig et0 down
ifconfig et0 detach
rmdev -dl et0
rmdev -l en0 -d ( to remove the definition)
rmdev -dl ent0 (to remove the card itself)
cfgmgr ( to reconfigure equipment and drivers or reboot)
NOW you can go into smit minimal configuration and add your changes.
REMEMBER to add your cable type. Also remember you only go into minimum
configuration for the main ethernet card. It is further configuration for
additional ethernet cards.
-------------------------------------------------------------------------------
Check the speed of the card... 10 or 100 or auto...auto is not a good option
and also half and full...make sure it matches your network...
smitty devices, communication, ethernet adapter.... set the change to database one feature to "yes" or do this step before you go into minimum configuration...after running cfgmgr.

------------------------

It could also be that ipforwarding by default is set to off...

Make sure you have the ipforwarding on? default is off..

no -o ipforwarding=1
do a no -o ipforwarding and see what it is set at? To make permanent add to /etc/rc.net
