    My setup:

    Vmware Host (eth0) --- iptables (NAT) --- Vmware GuestOS (vmnet1 :: 192.168.101.0/24)


    My iptables config:

    Code:
    # Masquerade all traffic (allow NAT traffic through VM Guest)
    # vmnet1		host-only network		192.168.101.0/255.255.255.0
    
    iptables --table nat -A POSTROUTING --out-interface eth0 -j MASQUERADE
    iptables -A FORWARD --in-interface vmnet1 -j ACCEPT
    iptables -A INPUT -i vmnet1 -s 192.168.101.0/24 -d $SERVER_IP -j ACCEPT
    

    I would like to access SAMBA (this sits on the Vmware Host) from within Vmware GuestOS.
    e.g. \\192.168.101.1\SAMBA


    I'm at a lost at how to configure the iptables to grant this access from the Vmware GuestOS.

    Any help or recommendations will be kindly appreciated.

    You must open the ports 137 - 139.
