Port redirect

Post by rflribeiro » 2007/04/16 13:55:13

Hi all and sorry for bad english. In my CentOs 4.4 i have a VMware Windows 2000 Pro with a Ms Sql Server installed and available to external connections via port redirect:

iptables -t nat -I PREROUTING -p tcp --dport 1433 -j DNAT --to-destination 192.168.1.3:1433 .
It was working perfectly, but doesn´t work anymore with CentOs5.

Other thing: how to check my internal eth device as trusted device? That is the device that is bridged to VMware network device. Can someone help me? I´m not a Linux Admin, i´m DBA and this machine is in my home. Thanks in advance.

Can't really help you but we had roughly the same problem on RHEL5 and backed away because VMware is considered experimental with RHEL5. I have never completely figured out what the problem is but there appears to be a networking issues with VMware (On RHEL4 this is the way it started out also, little network gotchas. I thought I had misconfigured something and was talking to another VMware user and he reported the same thing, specifically NFS).
You might try creating a Xen Centos4_4 and installing VMWare in there and put your Windows box inside of it.
