Interesting challenge getting SSH from outside to my VMWare guest

Hi,

I'm working on getting more acquainted with VMWare and the SUSE SLES OS, so I've downloaded and created a guest running SLES 11 SP1. This works great, no problems. However, there's some funny-ness (is that a word?) when I'm attempting/testing to SSH from outside my local LAN into the guest.

Let my sum up my setup:

The VMWare server
- Is a Windows 7 with LAN-ip 192.168.1.66 (static).
- The guest is running with a bridged configuration, not NAT.
- Windows Firewall has been disabled in an attempt to get some data in the SUSE firewall logs.

Another PC in my LAN
- Is also a Windows 7 with LAN-ip 192.168.1.65 (also static).
- Connects just fine to the VMWare guest on 192.168.1.77 (see next section).
- Has Windows Firewall running fine (also attempted to disable)

The SLES guest
- Is configured with LAN-ip 192.168.1.77 (also static, obviously).
- SSH port has been changed from 22 -> 1337.
- The SUSE firewall allows SSH from 192.168.1.0/24 to make it accessible from my LAN area (this is going to be narrowed down later, just to please the security minded people Smilie)
- The SUSE firewall DOES NOT allow SSH from outside the LAN, but should be allowed on a IP-by-IP basis.

External Linux Debian VPS
I have an external Linux Debian VPS solution. When I ssh to my WAN IP from this, and supplying port 1337, it just eventually times out, clearly indicating something's amiss somewhere in my configuration.

My ISP-provided router setup
- Portforwards port 1337 to 192.168.1.77

So, what I'm pondering about is what I can try to get the traffic actually arriving at my guest. I have read alot about running the guest in NAT configuration and then using the VMWare tools to portforward port X to the VMWare's assigned IP address.

I am not really very experienced in networking (which is why I'd really like to avoid a NAT solution until I get a hold of stuff), but I have the idea that if I without further ado can access my VMWare guest from my local LAN just by providing the statically assigned IP, I would figure that I'd get it off just by portforwarding the assigned SSH port directly to my guest's IP?

I hope that I have provided sufficient information but if not I shall happily provide additional details as necessary. I hope that you might be able to push me in the right direction

VIRT-CONVERT(1) 					   Virtual Machine Install Tools					   VIRT-CONVERT(1)

NAME
virt-convert - convert virtual machines between formats SYNOPSIS
virt-convert [OPTION]... INPUT.VMX|INPUT-DIR [OUTPUT.XML|OUTPUT-DIR] DESCRIPTION
virt-convert is a command line tool for converting virtual machines from one format to another. Pass in either a VM definition file (such as VMWare vmx format) or a directory containing a VM. By default, a new VM definition file, and converted disk images, will be placed in a new output directory. If an output directory is specified, it will be created if necessary, and the output VM definition placed within, along with any disk images as needed. If an output VM definition file is specified, it will be created alongside any disks in the same directory. OPTIONS
Any of the options can be omitted, in which case virt-convert will use defaults when required. An input VM definition or containing directory must be provided. By default, an output directory is generated based upon the name of the VM. The default input format is VMWare vmx, and the default output format is a libvirt "image" XML definition (see virt-image(5)). -h, --help Show the help message and exit Conversion Options -i format Input format. Currently, "vmx", "virt-image", and "ovf" are supported. -o format Output format. Currently, "vmx" and "virt-image" are supported. -D format Output disk format, or "none" if no conversion should be performed. See qemu-img(1). Virtualization Type options Options to override the default virtualization type choices. -v, --hvm Create a fully virtualized guest image Convert machine to a hvm/qemu based image (this is the default if paravirt is not specified) -p, --paravirt Create a paravirtualized guest image Convert machine to a paravirt xen based image General Options General configuration parameters that apply to all types of guest installs. -a ARCH, --arch=ARCH Architecture of the virtual machine (i686, x86_64, ppc). Defaults to that of the host machine. --os-type=OS_TYPE Optimize the guest configuration for a type of operating system (ex. 'linux', 'windows'). This will attempt to pick the most suitable ACPI & APIC settings, optimally supported mouse drivers, virtio, and generally accommodate other operating system quirks. See virt-install(1) for valid values. --os-variant=OS_VARIANT Further optimize the guest configuration for a specific operating system variant (ex. 'fedora8', 'winxp'). This parameter is optional, and does not require an "--os-type" to be specified. See virt-install(1) for valid values. --noapic Override the OS type / variant to disables the APIC setting for fully virtualized guest. --noacpi Override the OS type / variant to disables the ACPI setting for fully virtualized guest. Miscellaneous Options -q, --quiet Avoid verbose output. -d, --debug Print debugging information --dry-run Proceed through the conversion process, but don't convert disks or actually write any converted files. EXAMPLES
Convert a paravirt guest from "image.vmx": # virt-convert --arch=i686 --paravirt image.vmx Convert a 64-bit hvm guest: # virt-convert --arch=x86_64 vmx-appliance/ hvm-appliance/ AUTHOR
