Interface says offline even though it isn't

I understand what you mean and without getting into how many simultaneous connections your your SOHO equipment can handle or whether its junk or not, I have a separate question.

How do you get fail over using a single ISP (comcast) and especially if its coming off 1 piece of coax?

I could see getting 2 comcast modems and aggregating the bandwidth for faster speeds, but I'm not sure how you can get failover using a single ISP's infracture?

Yeah it's kind of silly, but sometimes the occasional t4 timeout can cause a modem reboot and it can get kicked to the 2nd modem. I have a DSL modem as a backup as well, so it's all good.

My only real issues with his particular setup are:

1. Double NAT breaks UPnP and NAT PMP.
2. Unless I'm missing something it offers no redundancy outside a fried modem.
3. Introduces another point of failure (router).
4. Probably introduces a much smaller state table between the modem and pfsense than pfsense has which is a really big deal for P2P.

As for why his interface is reading as Down, I bet the previous commenter was right. Packet loss.

So, you have primary comcast modem directly into pfsense, then failover to comcast modem > router > pfsense, then DSL > pfsense?

In that order of precedence?

This thread is plain hopeless. Now we have DSL in play as well… we started with one cable modem going "down"...

@OP: Stop wasting people's time and post relevant screenshots of your configuration if you want any help. This gets beyond silly.

Please refrain from being rude. If you think it is a waste of time and do not wish to participate in the thread, then don't. Nobody forcing you too. Don't believe the OPer ever asked for an opinion of the setup. Not everyone is at your level of networking knowledge, nor have your same objectives, and learning is rarely silly or waste of time.

I was going to recommend he make the NON-NATed comcast modem his primary, NON-NATed DSL his secondary and NATed (with router) redundant comcast 3rd in line.

I don't know enough to be rude to anyone else (-:

We are at post 22 now, and know exactly zero about the actual configuration in place. The target of the thread has meanwhile move from a dead simple pf => cable modem to 3 WANs with unspecified configuration (was load balancing originally, then allegedly failover, and god knows what's really set up there. As a bonus we got another redundant router in place somewhere… I cannot see what's anyone learning here, beyond how not to ask questions if you want to get something solved.

Actually a few posts back seem to indicate that the OPer learned quite a bit.

All those details being asking for are not always necessary in order to provide guidance to enable the student to proceed with their learning. Sometimes they just need pointing in the right direction so they can figure it out instead of having the answer handed to them on a silver platter.

I am not sure why there is still discussion. I just removed the wnr3500l and all is well.

I just hid it because my two modem seemed to be too complicated and I didn't want to make it even more complicated since the problem was not related to the fail over, just the wnr3500l.

Thanks again, no need to angry.

kejianshi

I wasn't angry. Glad it works.
