Hope you can shed some light on this guys.
I'm working on a connection for a client, who has a Draytek 2850 with an FTTC connection from WAN port 2 that goes in to the ISP provided modem (PPPOE), and a PPPOA ADSL connection with o2 Business as a backup/failover. (WAN1)

The FTTC connection works perfectly fine but I can't get the ADSL connection to work.
For troubleshooting purposes I have set connections to "always on", which means I should be able to ping both IP's, correct? I will eventually change WAN1 to "backup" when WAN2 fails when both connections are working.
If I go to "online status" in the router, both connections are receiving an IP address and both appear to be receiving packets but I can't ping the ADSL IP.

Any ideas what I'm doing wrong? I've called o2 on numerous occasions to check things like username/password and multiplexing method etc. All appears to be fine. I wouldn't receive an IP if the password was wrong would I?

Sorry what do you mean? I'm trying to ping both WAN IP addresses from my PC. I'm accessing the router via HTTPS.

Does 0 RX packets suggest it's not even connected then? I presumed it would be 0 unless I set load balancing up.
 
I would have expected some RX packets as part of the PPP Session initiation. Unless the Draytek does not report RX packets which are generated prior to the PPP session being established.

Ping from your computer which is where....inside the 2850 network, outside of it?

What do the logs say?

Have you even tested if the failover works at this stage? Just pull the FTTC connection and see if the failover works as expected?

Nothing looks wrong from the picture you have attached. Are you sure that interface is set to respond to pings? Static or dynamic IP?

Outside of the network. Ping definitely enabled in the router. Static IP.

Just because it's enabled does not necessarily mean it will work. The ICMP packets need to route back to you, and Multi WAN configurations are never simple.

Just test the ADSL works alone without the FTCC connected first. Then go from there.

I can't even ping 8.8.8.8 though from the router diags.

I expected to have to go out and physically inspect the router/cabling but thought it was worth a try remotely first. I fully expect it to be something really simple though as there's a lot of confusion regarding router settings since Sky bought out o2 BB.
 
If Sky are involved there's a chance that the connection is using MER authentication.

I have seen mention of DrayTek supplying tweaked firmware on request, and it's possible they've now included MER support as a default option.
 
0 RX packets on the DSL interface is definitely not normal - try the 211801 modem code since that's pretty much the most reliable, or you could try the 252901 modem code since it's the newest (they're usually made for DSL compatibility problems).

0 RX packets makes no sense at all though since the PPP connection came up so it could be a firmware bug, try the 3.6.6.1 firmware from here:
ftp://ftp.draytek.com/Vigor2850/Firmware/v3.6.6.1/Vigor2850_v3.6.6.1_AnnexA/

Regarding MER, the 2850 does work with that but that connection definitely appears to be normal PPP otherwise it just wouldn't come up.

edit: although I don't think it's the router at fault so much in this case, try enabling dual DSL mode on that router (it probably has it) cos I've seen that help with DSL weirdness as well.
 
I'm using PPPOA, not MER.

I have now changed the login password to [email protected] after some googling, and I'm showing 15 RX packets, but still can't ping any external IP addresses from WAN1. grrr

Pinging through WAN1.
Pinging 8.8.8.8 with 64 bytes of Data through WAN1:
Request timed out !!!
Request timed out !!!
Request timed out !!!
Request timed out !!!
Request timed out !!!
Packets: Sent = 5, Received = 0, Lost = 5 (100% loss)
 
The install connection is very likely to have a 172.16.x.x address, not internet routable. It does seem like something on the ISP end if it's doing that though.
 
the [email protected] seems to be a common thing, with users stating it's working fine. What makes you think it'd give you a 172. address? Seems to be giving me a 93. address.

I think I'm going to try a firmware upgrade before calling it quits. Will it work OK doing it over the internet using "Web Firmware Upgrade" or shall I place the firmware file on the local network first?
 
I'm not on O2 but I assumed it was a test account as that's what would generally happen :)

Upgrading the firmware over the internet via the web interface is OK but the best option is to remote manage a local PC and do the update that way, it updates much quicker that way.
 
If i use the install account I get a dynamically assigned IP and the RX packets goes up. If I use the o2 username and password I receive the same IP every time but RX packets stays at 0, but still no connection with either.

I don't get it. It shouldn't matter about the internal cabling should it? The draytek is plugged straight in to the phone line, nothing else in between.
 
Cabling isn't an issue, you're getting sync and authenticating onto the network.

It's possible that you're being given the wrong gateway. What happens when you traceroute to an address from the DrayTek?
 
Are you logging on via the router web interface or have you tried to telnet to the device and check other features in the command line?

There are numerous show commands, etc... that will help you look into it further.
 
I don't think it's a router issue. Am on site now with the provided o2 Thomson router and still nothing. On the phone to o2 tech support now.
 
Is anything left alive from o2? All wholesale connections we had with o2 are gone - have Sky not finished migrating customers off the old BE/o2 network?
