command=createPortForwardingRule&response=json&sessionkey=FmHQb9oGmgKlM4ihB%2Fb2ik7p35E%3D&ipaddressid=d29bebfe-edc1-406f-b4ed-7a49c6e7ee1f&privateport=80&privateendport=80&publicport=80&publicendport=80&protocol=tcp&virtualmachineid=cc5c9dc4-3eeb-4533-994a-0e2636a48a60&openfirewall=false&vmguestip=192.168.1.30&networkid=5e56227c-83c0-4b85-8a27-53343e806d12&_=1391510423905

vmguestip=192.168.1.30

api/src/org/apache/cloudstack/api/command/user/firewall/CreatePortForwardingRuleCmd.java
@Parameter(name = ApiConstants.VM_GUEST_IP, type = CommandType.STRING, required = false,
    description = "VM guest nic Secondary ip address for the port forwarding rule")
    private String vmSecondaryIp;

@Override
    public void create() {
        // cidr list parameter is deprecated
        if (cidrlist != null) {
            throw new InvalidParameterValueException("Parameter cidrList is deprecated; if
you need to open firewall rule for the specific cidr, please refer to createFirewallRule command");
        }

        Ip privateIp = getVmSecondaryIp();
        if (privateIp != null) {
            if ( !privateIp.isIp4()) {
                throw new InvalidParameterValueException("Invalid vm ip address");
            }
        }

        try {
            PortForwardingRule result = _rulesService.createPortForwardingRule(this, virtualMachineId,
privateIp, getOpenFirewall());
            setEntityId(result.getId());
            setEntityUuid(result.getUuid());
        } catch (NetworkRuleConflictException ex) {
            s_logger.info("Network rule conflict: " , ex);
            s_logger.trace("Network Rule Conflict: ", ex);
            throw new ServerApiException(ApiErrorCode.NETWORK_RULE_CONFLICT_ERROR, ex.getMessage());
        }
    }

utils/src/com/cloud/utils/net/Ip.java
public boolean isIp4() {
        return ip < Integer.MAX_VALUE;
    }

public Ip(String ip) {
        this.ip = NetUtils.ip2Long(ip);
    }

=== ip2long for 192.168.1.30 => 3232235806

=== Integer.MAX_VALUE => 231-1 = 2147483647

3232235806 (192.168.1.30) is therefore bigger then MAX_VALUE making isIp4() return FALSE and
throwing a InvalidParameterValueException…
