Dual (2)WAN / Multi (9)LAN Routing Issue with Public IP's
-
having trouble with routing…
have attached a diagram...
i use to run two ubnt edge lite routers, i wanted to remove them and merge both upstreams into one box...
so now everything is connected as in attached diagram...
2 problems…
problem 1, can't get 204.101.*.208/29 working unless i check routing only platform (once checked i loose nat'ed clients) (SOLVED POST#11)
problem 2, blue subnets can't communicate to other blue subnets… (SOLVED POST#32)
firewall/rules set to allow all..
VIP/Proxy ARP set for both upstreams…
system/routing default gateway isp1
pink subnets firewall rules set GW default...
blue subnets firewall rules set GW as isp2...
can pfSense do this or will i need to remove nat'ed clients subnets to another pfsense box to allow route only platform?
when connected to blue subnet and check at google whats my ip, the right ip appears but can't communicate to other blue subnets
when connected to pink subnet and check at google whats my ip, only the 67.69..254 shows even when connected in 204.101..208/29 pool
can post more info/screenshots as requested if need be….
not sure what i'm missing here but after many searches on forum and google, i've broke down and posted here :(
when i was using the two ubnt egdemax lites eveything was communicating fine between the two different upstreams... so i can only guess i missed something somewheres in pfsense.....
EDIT: new issue noticed, goto post Reply #33 https://forum.pfsense.org/index.php?topic=83413.30

It will only NAT if there are NAT rules. You will absolutely have to enable manual outbound NAT and only have rules for the networks/interfaces you want to NAT for.
Any possibility you can start smaller during some dead time and work one WAN/one LAN at a time until get get more familiar with what pfSense needs?

i will give a try at 4/5am to add nat rules & switch to manual nat… (production enviro)
before this setup i had...
isp2 i've had on pfsense hardware before, everything was great, then tried the edgemax... worked but missed features pfsense had...
isp1 i had two pfsense vm's, first was route only platform, second used for nat'n clients behind single ip from /29 pool...
surffered hvac failure in room, edgemax baked, vm mechine toasted raid card... etc etc etc...
so as a last minute get everything back online i decided to go multi wan single hardware... i figured i missed something, thx for pointing out the manual outbound....
will post update in morning....
-
Ok. You will do it in the opposite order though - enable manual outbound NAT then tweak the rules.
I am pretty sure you can enable manual outbound any time. All of the rules that are placed there by the automatic process will be there so there should be no change in behavior until you start tweaking rules. Also keep in mind that you can just disable the ones you don't want instead of deleting them.
You should see two rules for each LAN interface. One with a static port for IPsec and one for everything else. I'd just duplicate those for interfaces you want to NAT for.

good morning…
so it's 5am here... (5:30am by time i post this)
i set manual out bound, set nat rules...
connected to pink ip pool, googled whats my ip, still came up with pink gw ip.... when connected to blue ip pools (tested three subnets) proper ip showed...
:(
so since i was here, i checked route only platform... and two things happened... google showed the ip from pink ip pool, and blue subnets could talk to each other... but nat'ed clients no access to net....
so i'm a little baffled here....
edit: also rebooted just incase... same resault after....
-
Screen shots of Firewall->NAT->Outbound and Firewall->Rules (Interfaces) please. You have something not right. Routing Only Platform is not what you want.
-
ka… snapshoots attached..... firewall rules same for both nat'ed subnets...
-
Why are you natting your public IPs?
-
no reason, forgot to remove it…. trail and error trying different things.... cleared it out now... just 172.16.5.0/172.16.10.0 in there now...
-
OK. And what, specifically, isn't working now? Let's work one LAN/WAN interface at a time.
-
first problem…
isp1,
204.101.*.208/29 subnet...
when connected to ip in that pool, i goto google and search whats my ip.... should show 204.101..209, but shows isp1 pfsense gw ip 67.69..254....
lan_bell = 204.101.*.208/29 subnet
-
With those NAT rules it would do that. Without them it should not. Did you clear states after deleting the NAT rules? You can clear only the states in question by filtering on 204.101.*.209.
I wouldn't have the Proxy ARP VIPs. I'd have type Other - if you need any at all. Out of curiosity, what is the IP address of the LAN_BELL interface?

my bad for typo… 204.101..209 should have been 204.101..208/29 meaning a ip from that pool....
ka i changed VIP to other... checked and is now working..... THANK YOU…. i swear i tried that once but must have over looked....
i will try changing the other isp2 vip setting in a minute and see if that changes the block between isp2's smaller subnets....
-
okay, so both VIPs are set to Other, and seem to be okay…. connected to different pools and whats my ip was correct in all tests from all pools....
while i was connected to pool 216.185..192/26 i tried to access email server in 216.185..160/27 pool with no success.... while connected to a pool fed from isp1, i could access with no prob... when tried from a pool feed by isp2 only time i could access email was while i was inside same pool as server....
here attached are the screenshots of firewall rules for both...
-
Check all your netmasks and gateways. What happens when it fails? Anything in your firewall logs?
-
all netmasks correct… doubled checked with online subnet calculator...

-
What routes have you put in System->Routing ?? You probably want to get rid of everything.
-
zero….

When you traceroute it what IPs is it bouncing between?
-
now this is where it gets funny….

used http://network-tools dot com to get this
isp2 should have went 216.185..110 then to 216.185..1 which is the isp2 gw i connect to... then 216.185.*.2 which is my pfsense box
