Need help understanding pfSense from a Cisco perspective
-
Hi,
I have years of experience with Cisco and feel like I'm relearning basic concepts using a new paradigm with pfSense, if anyone can help translate what I have configured on my Cisco equipment to pfSense concepts I would be much obliged.
I have my Cisco 2911 router setup with g0/1 as the public address for my network, and g0/0.48 as the LAN side of my network. I configured DHCP and NAT (PAT) between the two interfaces, inside and outside appropriately.
I then have a Cisco 2960-S connected to g0/0 configured as a trunk port, and then all the ports that computers are plugged into are access ports for VLAN 48. Everything works on this setup, and it would seem to be the simplest possible network that could be configured, short of using subinterfaces; which I think might be tripping me up in my conversion to pfSense terms.
We are changing over to an XG-7100-1U since the 2911s are EoL, and I am having no luck trying to configure it using my old tricks. Going through the wizard automatically gives me VLANs 4090 for the WAN interface and 4091 for the LAN interface. I am assuming that these correspond to physical interfaces eth1 and eth2, but they are defined as part of an aggregation port called lagg0?
Are these virtual interfaces like a subinterface on a Cisco router? I tried changing the VLAN on the LAN interface to 48 and I couldn't get into the web management anymore, so I did a reset from the console. Also it looks like lagg0 is referencing another interface called OPT3......what??
The port numbering seems to be a bit varied as well between the physical and the logical, something might be called port 0 in the web interface, but that might reference eth1?
I've also tried setting up a different subnet for the LAN that I'll use for management, and then configuring the private range that we will use and assigning it to VLAN 48 on lagg0, but I don't even seem to be making connection between that port and the DHCP server as I get APIPA.
I don't want to go on anymore about all the things I'm confused about, because I'm hoping just a hint of what I should be looking for will put me on the right track and I can figure the rest out from there. I can't be the only Cisco minded person making this transition, any help you can offer would be appreciated!
