- how big is your currently maintained network with pfSense (how many IPs, how many networks, how many VLANs)
I am looking into the network administration of a company in USA. Implemented IPv6 for them on pfsense. /24 subnet and 3-4 VLANs
- how is your pfSense connected to the IXP (bandwidth, technology, redundancy)?
Each data center has redundant pfsense firewalls and cisco equipment.
- how is your pfSense connected to the internal network (bandwidth, technology, redundancy)?
On each data center pfsense is connected to LAN switches.
- how many pfSense setups have you done in the last 2 years?
As mentioned earlier, I did IPv6 setup in last 8 months for 3 data centers of company
- how you ensure ongoing documentation of firewalls (topology, nat and firewall rules) with multiple administrative persons?
change in firewall is followed by approvals from the management. After the changes are made after approval, the password will be changed and will be shared when next approved requirements comes.
- what is the best practice for IPv4 and IPv6 setup?
depends on many things. Come up with your current environment and i will tell you the best design.
Thanks
