Unable to use Static IP/Gateway for WAN

[eri--]

Check that you do not have block bogons on the interfaces.

[gazzer82]

I am done in the office for the day so i can't check the live server, however i have the config.xml backup file with me, can i check in that, what XML key would i be looking for?

[gazzer82]

I have double checked and i do not have block bogons selected on any of my interfaces.

Any other ideas?

Hello, I think I am facing the same problem

my testbed setup:

modem1->full bridging mode
modem2->half brigding mode (ip 82.xx.xx.17/29

fxp0->WAN1 (static ip) 75.xx.xx.xx/20
lan->LAN (static+dhcpd set for clients) 10.0.0.0/24
opt1->WAN2 (static ip) 82.xx.xx.18/29

I have created routes for both WAN's

WAN1 wan1  78.105.0.1  78.105.0.1

WAN2 (default) wan2 82.152.129.17 82.152.129.17

then I created a gateway group

dualwan  wan1
wan2
Tier 1
Tier 1

I then amended the existing LAN firewall rule and set the gateway to dualwan

Proto  Source  Port  Destination  Port  Gateway  Queue  Schedule  Description 
[add new rule]
[click to toggle enabled/disabled status] * LAN net * * * dualwan none   Default allow LAN to any rule

with this configuration, i am facing the same problems as gazzer82, I get no network connectivity, pinging  my half bridged modems ip (wan2) i get 100% pkt loss, if I then go back to the firewall rule for LAN, setting the gateway to "default" works fine, setting it to anything else is a no go.

I am using the latest snapshot

P.S I also have bogon's turned off, though i dont think it really related to this, I will also download latest full iso and start from scratch incase my present box is borked.

Try to set a default gateway and Firewall: NAT: Outbound manual outbound nat. For me this fixed the problem.

[gazzer82]

Hi XToni,

i have tried you suggestion with no success, i can now ping the gateway ip from the pfsense box, but i cannot ping from pfsense to the outside world, it is very very odd.

Firewall rules wise, all i have is an allow all from Lan to Wan using the default gateway, otherwise i loose access to the web config interface, then above that a rule which specifies that any traffic not destined for the pfsense ip (192.168.20.254) should be routed out of the static gateway i have set.

I have enabled DNS forwarder, and setup two DNS servers in preferences, OpenDNS with ip's of 208.67.222.222 and 208.67.220.220.

I have tried turning Outbound NAT to manual, leaving the default rules there and not changing/adding any rules here, do i need to?

Is there something in this config that is causing the problem?

I am just confused as to why when i set the interface to DHCP it works fine, but by manually specifying exactly the same config it does not work.

Cheers

Gareth

[XToni]

Go to System:routing:gateways, edit your gateway and choose default.

If nothing change Go to System:Advanced:Firewall and disable the entire firewall to see if it's a firewall issue.

[gazzer82]

Ha ha, we are getting somewhere, followed all of your steps.

As long as i set my gateway as default, and make sure that my firewall rule for gateway is set as use default, i finally have internet access.

However, if i set my firewall rules gateway to manually point at the correct gateway i get no net access. This is a problem as i am eventually going to be setting this up as a load balanced dual WAN so i need the ability to put the two gateways into a group and tell my firewall rules to use that group, not the default.

Any idea?

Do i need to create additional firewall/nat rules to make this happen?

Help very much appreciated!!

Cheers

Gareth

[kpa]

When you set the WAN addresses manually, make sure you have the netmasks set correctly for each wan interface, /20 for WAN1 and /29 for WAN2 based on your description.

[gazzer82]

thanks kpa, i did have the netmask set at 24, i have tried it at 20, but at the moment i am only using a single WAN for testing. However it hasn't helped things, i am still able to acces the net fine setting the gateway in the firewall rules to default, but setting it manually to my actual gateway leaves me with not access outside the network. Interestingly it appears that in this setup pfsense also cannot get to the net, from pfsense i can ping the gateway fine, but if i try to ping anything outside the gateway, be it by ip or dns name i get 100% packet loss.

By the way, for the sake of testing at the moment this device is still sitting behing my nat router, this is what i am using for the gateway, not that that should make any difference.

Anyone else got any idea, can anyone explain to me what the difference in rules/routing are between leaving the gateway set as default and manually selecting the gateway, see if i can work out where it's going wrong/getting blocked!!

Cheers

Gareth
