Replacing Cisco 1841 with PFsense
-
Hi all,
Many years ago, I setup a Cisco 1841 for client to route a public range from their ISP to the internal firewall. That 1841 maxes out at Fast Ethernet on both Ethernet interfaces so it's time either to upgrade to a new Cisco router or, possibly, replace it with a PFsense based solution as the business wants to go well above 100 Mbps from their ISP. I use PFsense as a firewall / NAT router all the time so I'm fairly well versed in its use. However, I'm a little weak on whether this is a good idea or not. Those Cisco's are simple and reliable - they just run forever it seems without a hitch. Then again, PFsense has proven itself to be reliable as well.
Here's most of the running config on the Cisco:
service tcp-keepalives-in
service tcp-keepalives-out
service timestamps debug datetime msec
service timestamps log datetime msec
!
no aaa new-model
!
no ip source-route
ip cef
ip tcp synwait-time 10
!
interface Null0
no ip unreachables
!
interface FastEthernet0/0
description $ETH-WAN$
ip address 209.1.83.70 255.255.255.252
no ip redirects
no ip unreachables
no ip proxy-arp
ip route-cache flow
speed 100
full-duplex
no mop enabled
!
interface FastEthernet0/1
description $ETH-LAN$
ip address 209.0.231.33 255.255.255.224
no ip redirects
no ip unreachables
no ip proxy-arp
ip route-cache flow
speed 100
full-duplex
no mop enabled
ip route 0.0.0.0 0.0.0.0 209.1.83.69
!
endSo, my feeling is that this is feasible as it's really a simple function. Any advice or recommendations on a corresponding PFsense based configuration?
Thanks,
Matt
