Problem with bitmask 30
My ip config:
When i configure pfsense with it (bitmask 30) i can ping modem (141) but nothing behind him.
When i use bitmask 2 i can ping some www site. All port are blocked by modem.. When i use bitmask 29 i can ping all and any port aren't blocked.
I dont uderstand it.. Why it work on other netmask?! And why not work on my mask??
It should be configured with whatever your ISP gave you to put in. A netmask of /29 vs /30 changes the network id.
You also said "When i use bitmask 2 i can ping some www site"…. what is "bitmask 2"?
bitmask 2 i mean /2
When i use /30 (like i get from my ISP) it wont work… (on tp-liink router 255.255.255.252 works well, on pfsense wont work)
We're missing some details… So, when you were on your tp-link router was your WAN set to DHCP? Or are you paying for a static IP block?
/2??? A mask of /2 would include almost every IPv4 address out there.... you wouldn't be using that.
