Many blocked IP from the same person?

I think you are right its a gateway. The gateway that i have is a technicolor heres a pic of the setup

[johnpoz]

still didn't really answer my question.. Does pfsense actually have a public on its interface, same with your netgear dd-wrt or are they on a natted network from your isp gateway??

go to pfsense interfaces..

[killmasta93]

Yep it does, Also by the way i have been trying to block that IP but without the logs i tried
Disable the checkbox "block RFC1918" on the WAN-config page.
Create an alias containing 10.0.0.0/8, 172.16.0.0/12 and 192.198.0.0/16.
Create on your WAN a new block-rule with as source any and as destination the previously created alias.

But no luck  :(

Disable the checkbox "block RFC1918" on the WAN-config page.
Create an alias containing 10.0.0.0/8, 172.16.0.0/12 and 192.198.0.0/16.
Create on your WAN a new block-rule with as source any and as destination the previously created alias.

That's because the traffic into your WAN is sourced from the address in question and destined for your WAN address.  You have pass source any dest RFC1918 so it's not going to match.

What you want is to leave the block RFC1918 traffic enabled on WAN.

If you don't want to see it logged, either put another block rule for the specific source IP address on WAN without logging (put it at the top) or turn off the logging for those block rules in Status > System Logs > Settings

thanks silly me  ;D

[johnpoz]

So who says its not your gateway sending out that traffic?  What makes no sense is that 50K packets would come from the SAME ip.. Seems like a bug in the dhcp client.. That would not be a discover packet but a renew packet since its sourced from IP and not 0.0.0.0

I would take it coming from your gateway device. What is the mac of the packet..  Does it match up to what your gateway device is?  Is your ddwrt device seeing these packets?

[killmasta93]

well i ran wireshark on both network. But nothing from that IP but I think your right the gateway is trying to renew its IP from the 181.xx.xxx because originally its not static maybe that could be the cause?

Also had to uncheck on settings logs the option of Log packets blocked by 'Block Private Networks' rules for it not to log that 10.141.5.1

Thank you

[johnpoz]

those are different source macs… Where did you sniff that at?  pfsense wan?  Are you seeing 50K of those packets again?

00:24:b2 is netgear.. hat is prob its lan with that 192.168.1.1

that other mac is

Hon Hai Precision Ind.Co.Ltd
Address
    Taipei Hsien 236
    TAIWAN, PROVINCE OF CHINA
Range
    D0:27:88:00:00:00 - D0:27:88:FF:FF:FF
Type
    IEEE MA-L

Which have no idea what that is..

[killmasta93]

yeah my bad i forgot to sniff the gateway from my lSP now i see the DHCP renewing but not the 50k packets. Im pretty sure my lSP is trying to renew my WAN of the 181.xx.xx.xx  :(

Also whats curious is that my gateway is on bridge mode which in theory It should not give me DHCP when connecting though wifi to my lSP gateway?
Or am i Completely  wrong?

[johnpoz]

Your isp doesn't renew anything  A client when about 50 of its lease or when told to via dhcp options will attempt to renew.. This comes from the dhcp client.

Why are you showing what looks like public IP but then also 10.141.51.1 address?  So is it getting renewed or is it sending every few seconds still?

[killmasta93]

so the public IP is the 201.xx.xx.xx im not sure why it shows 10.141.5.1 now heres the weird part So I can also connect though WIFI to the gateway and and shows something totally different. see Picture. Also the 10.141.5.1 I have it turned off the logging im sure its still blocking.
is this even possible to have this IP? Im just confused how I have internet when the gateway is on bridge mode and I am able to connect directly though WIFI.

[johnpoz]

that is a public IP with a very large mask /18 man that is big mask.. Yeah if ts bridge mode you would get IP from isp over wireless..  Normally you only get 1 IP.. It seems odd that you have 2 different IP blocks there you were seeing.

[killmasta93]

its very weird  :o but on the bright side I got 2 static public IP  ;D

Thanks again Johnpoz for all the help  :)

You might find one is actually static for server hosting purposes like web & email, remote access/vpn etc, the other if in a different range is variable so you can surf the web with an element of privacy, at least thats what UK ISP's do anyway, but as I also discovered when ISP's hand out an IP block when ordering a single static ip, the ISP have in fact given all the ip's in the block. Whether your ISP have done this if its so large, only you can find out by setting up pfsense to accept incoming on the other ip's in that block, or they may have some other setup upstream to restrict you to one ip.

Have a poke a round if interested in finding out.
