(SOLVED) Can't have access to Google's 172.217.0.0 addresses
-
@torisevt said in Can't have access to Google's 172.217.0.0 addresses:
WAN(dhcp) and LAN(192.168.1.0/24).
What do you mean ?
Both WAN and LAN on the 192.168.1.0/24 network ?@torisevt said in Can't have access to Google's 172.217.0.0 addresses:
172.217.0.0
Keep in mind : hosts on the Internet have no obligation to reply to a ping.
edit : I just tried (one) 172.217.0.1 : it replies to ICMP.
-
WAN get it's IP from ISP DHCP.
And LAN uses 192.168.1.0/24 network.Sorry if problematic to read

pls provide screenshot of rules WAN / LAN of your pfsense

Do a traceroute to www.google.com. Are you getting past pfsense? Are you using IPS or vpn service?
Do you have any rule rules in floating?
Your allow subnet rule? So you have downstream networks of your lan?
You do understand that allow rule to 172.19/16 is pointless right, since you have any any rule.. Allow subnet rules since your any any rule source is any... vs say lan net.

@johnpoz
No rules in floating
Subnets are at the other site.
I try to fix the previous guys problems.
I had to change to gmail.com, because www.google.com IP changed to 216.58.207.228 which works fine.C:\Users\administrator>tracert gmail.com seurataan reitti isäntään gmail.com [172.217.20.37] enintään 30 siirräntävälillä: 1 <1 ms <1 ms <1 ms 192.168.100.1 2 * * * Pyyntö aikakatkaistiin.

And what is this 192.168.100? You stated your pfsense lan is 192.168.1
-
@johnpoz
Fingers type before I think.
We have 192.168.100.0 network at the site. -
Ok...So pfsense is 192.168.100.1
What does the routing table look like on pfsense? Do a traceroute from pfsense for that 172 IP.

All this means that "172.217.21.164" want to reply to me (my WAN IP).
Not a big issue if ICMP won't come back. -

62.78.108.37 137.688 ms 14.744 msThat trace looks odd, are you getting back multiple IPs on the same hop?
From your trace looks like your problem is upstream of pfsense.. To prove this too yourself - just sniff on wan of pfsense when you ping that IP... Do you see pfsense send the ping request with its public IP as source.. If you do not get an answer that is on your isp or upstream..

-
@Gertjan
It doesn't work when Google change it's sites IP addresses to 172.217.0.0 net -
He has 2 sites.. Only 1 site is unable to ping that netblock.
-
The site with no result (no ICMP returned) uses an upstream router with differnet settings ?
Another ISP ?Also : "Google" uses firewalls. When some networks (read : ISP clients) ping to much, it would not surprises me that Google throttles ICMP a bit for that network. It's just a free service ;)
-
There is a cable modem connected to pfsense that is connected to LAN switch.
No another ISP, unless IPsec VPN between sites? -

Ah !! Even more factors to check !!
You've got more such details ?
