The router that my ISP has delivered contains an IPv6 firewall. The only configuration option is whether it is on or off. Apparently, this firewall simply denies all incoming connections.
I understand this is to prevent exposing all hosts… Continue reading Is it dangerous to disable the IPv6 firewall built into many home routers?
Setup:
A(2001::1:123) <——> B(2001::1:124) <——> C(2001::1:125)
where A,B and C are the systems.And apply rule of NAT(SNAT/DNAT) on system B for forwarding a packets from C to B,B to C,A to B and B to A.
Is thi… Continue reading Is this NATing possible between IPV6 to IPV6 hosts? [on hold]
Apparently, for half a year already at least, my ISP has assigned me IPv6 addresses. I discovered this accidentally, while editing Wikipedia. So it seems my ISP started to support IPv6 addresses and decided it was a good time… Continue reading Do household IPv6 addresses introduce vulnerabilities?
I have a fairly simplistic pfSense setup. IPv6 is provided through a Hurricane Electric tunnel.
Something on my home LAN is sending traffic from an odd-looking address, and so it’s getting blocked, because my outgoing rules … Continue reading What is this "…ffff:ffe2" traffic being blocked?

Say I have a server running some version of Linux and I give this server an IPv4 address of 10.1.1.1
Now using my network firewall I NAT this IP to some public IP address and I block all incoming traffic to that IP except po… Continue reading IPv4, IPv6 and firewall

A router doesn’t support ipv6. There is a machine connected to the router, that is assigned an ipv4 address by the router. The machine uses firewall software.
Setting up the machine’s firewall, all incoming traffic to the machine needs to… Continue reading Blocking ipv6 packets with firewall, if using an ipv4 router
When moving into a new house, it’s important to arrange for the connection of basic utilities. Electricity, water, and gas are simple enough, and then it’s generally fairly easy to set up a connection to an ISP for your internet connection. A router plugs into a phone line, or maybe a fiber connection and lovely packets start flowing out of the wall. But if you’re connected to the internet through an ISP, how is the ISP connected? [Kenneth] answers this in the form of an amusing tale.
It was during the purchase of data centre rack space that [Kenneth]’s challenge …read more
