RV180 slow in router mode

Hi there

I've just bought a RV180 router.

The firmware is new:

Release 1.0.3.10

If I use the device in Gateway Mode I got speeds in test and downloads about 500Mbit/s, that would be good (tested directly at a 1Gig Backbone).

But I wanna use the device in Router Mode so that I can use different public IP's in the LAN. That works but the speed falls dramatically to onyl 70Mbit/s.

Why is that speed so slow? that's useless for me.

I have disabled all QoS/Security things which could affect the speed

RV180 slow in router mode

Michael,

I'm not sure what is causing the slow speed in Router Mode, you may want to open a case for that:

www.cisco.com/go/sbsc

Can you use One-to-One NAT to translate the public IPs to private IPs on the LAN? That might be a good workaround to get the speed that you desire.

Please reply if you have any questions.

Sounds like you've discovered a bug.  I'd use NAT one-to-one as a workaround, assuming it works at full speed.

RV180 slow in router mode

1:1 NAT doesn't work for me because I use a /29 IP block on the LAN side.

It's strange when I activate the router mode and reboot the router, the configuration is still in router mode but My client shows up with the IP Adress from the WAN interface and not it's own public IP.

If I unselect and select the router mode, the IP adress is then correct but the speed is terrible slow.

Michael,

1:1 NAT doesn't work for me because I use a /29 IP block on the LAN side.

How does using /29 affect One-to-One NAT? I'm thinking it should work just as well as a /24.

How many public addresses do you have?

RV180 slow in router mode

I have one public IP on the WAN Interface and I will use a PUBLIC /29 on the LAN side:

in example:

3.4.5.6/30 on WAN side

3.4.6.0/29 on LAN side

and the client on LAN side should be visible with the LAN IP's:

3.4.6.1 and 3.4.6.2.

Re: RV180 slow in router mode

Michael,

Use One-to-One NAT to translate the external IPs to internal IPs.

Firewall-> Advanced Settings-> One-to-One NAT

Private Range BeginPublic Range BeginRange LengthService

192.168.1.100                                   3.4.6.1                                              2                           Any?

That will translate 3.4.6.1 to 192.168.1.100 and 3.4.6.2 to 192.168.1.101 and forward all traffic accordingly.

You can also use a Range Length of 1 if you don't wish to use consecutive LAN IPs.

Re: RV180 slow in router mode

Hmm sorry that's not working

The real example is:

WAN IP: 86.245.121.126/29

LAN IP of Router: 86.245.121.249/29

Client in the Network behind has LAN IP 86.245.121.250

If I now configure NAT I got these errors:

Public IP should not be equal to WAN IP

or

Public IP Address should not be in LAN Subnet

Re: RV180 slow in router mode

Michael,

It is not working because you have a WAN IP configured on the LAN. You should use LAN IPs on the LAN side and allow the router to translate the WAN IP to the LAN IP.

192.168.1.100                                   86.245.121.249                                           2                        Any?

That is strange to see it showing as router mode either way on the interface--but it just goes to show you how many bugs there can be in these things!
