Accessing another network/device

i hope this i the correct forum for this question.

prior to having pfsense i used a linksys router with flash ddwrt firmware. flat network, no vlans. my comcast cable modem (gateway/standalone/not all in one) internet port connected directly to the WAN port of the ddwrt router and my network devices connected to the LAN ports or to a switch that was connected to a LAN port. LAN network was 192.168.1.0 /24 and everything worked fine. with the setup, as described above, i was able to login to my comcast device and check out diagnostic information using ip 192.168.100.1 from any network device with a 192.168.1.0 /24 address.

after my upgrade to pfsense (which i am very happy with) i am no longer able to hit 192.168.100.1 to see the comcast stats page.

my pfsense has a LAN address of 192.168.1.0 /24 and two vlans. the vlans networks are 10.10.10.0 /24 and 172.16.16.0 /24. currently, i am connected to the regular LAN getting a 192.168.1.xxx address. do i need to setup special routing to be able to hit the 192.168.100.1 device?

i dont know if it is a good or bad thing that i was able to do this with the ddwrt hardware. it is probably a good thing, i would rather have to have this be something that needs to be setup vs something that is wide open by default.

thanks and please ask any questions if i didn't elaborate enough.

In addition to the standard 192.168.100.1, my Comcast modem (a Zoom 5431J) also has a public IP address on the management interface that is reachable from the LAN on m0n0wall. Does your modem have such an address and if so have you tried it?

Also, you might try the suggestion here:

However, ignore the information regarding the PPPoE as it is not applicable to Comcast cable which is DHCP on the WAN.

not sure if it is accessible via the public ip, but i am sure it must be (if not for me, def. for comcast).

however, i have never had to go that far since 192.168.100.1 always worked.

thanks for the link, reading now.
