[Uverse] Upgraded static DSL to ADSL2+ -- Issues?

Just got upgraded to the ADSL2+, and had a few quick
questions.

1. New line has the Datapath set back to Interleaved instead
of Fast. Is the Direct forum is the best place to make
that request? (They fixed it for me a couple years back when
it got reset somehow...)

2. MTU. Is 1492 still the ideal value? The new NVG510 has
that set at 1500. Haven't adjusted the value yet. Quick search
provided a bunch of information, none of which was really helpful.

3. Retaining my old IP block after upgrade.

When the Support person set me up for this upgrade, I was informed
that they might be able to keep 1 or 2 of my old static IP's. lol

As expected, the new modem came with a new IP block, which I haven't had any luck using yet. (Been trying for 3 days now.)

However, as of 15 minutes ago a quick WhoIs check over at
NetworkSolutions.com on one of my old IP's still shows me as the
owner. I am also the owner of the new block which isn't working
right.

Is there a chance the techs in the Direct forum might be able to
switch me back to my old IP's? In the event that I get this
new modem working right, that would be very helpful.

Re: ADSL2+ Datapath, MTU & IP'block questions....

Interleaved is the default for uverse
The Direct forum is the only place to make
the request for a change?

1492=pppoe is for pppoe......you've been changed to dhcp and it's 1500

There my be a chance you'll get the old block back just ask.........

One quick way to get going is to use the nvg510's ip passthrough option on one computer, record the computers tcp/ip settings they can be used to configure other computers

Thanks for the reply.

I tried that with the passthrough option, but no luck.

With the setting at DHCPS-Fixed, it assigns the client IP and
and sets the Gateway address with values in the public block
but client has no internet access.

Attempts to manually assign the Public IP, and one of the
2 gateway IP's that work as mentioned in my first post fail.

Get a warning about the IP and Gateway not being in the
same segment.... No connect if I save the config anyway.

Did you try the dynamic setting?

That's the way your current block is supposed to be
There is a block for the modem's wan and there is the block you use each has different a subnet.

I did try that. It assigns my client a local ip and gateway
that is the exact same as the Broadband gets. That is
to say the IP that is not in public pool and is in a whole different
block.

Things work for that client, but that doesn't help me use any
of my public IP's.

Can you post the ip's that you're refering to?

The uverse public ip block setup is different from the pppoe public ip block setup.........
I think this difference halts your setup efforts
said by wayjac:

I'll try to explain the differences............
There is a block of three [1 useable] ip's for the modem/router only
And there is the block of eight [5 useable] ip's you will use
Each block is in a different subnet.

Thanks again for your feedback.

I finally got things more or less working now with the static
IP addresses.

When I turned the IP Passthrough off, clients I had configured
with static IP's in the assigned block were able to access the web.

The NVG510 I received, came with the Firewall/IP Passthough
options set for DHCPS-static and Manual.

The 5 Public IP's and Public Gateway IP were all in the
99.67.xx.xx range.

The IP that the NVG510 gets is in the 172.12.xx.xx segment,
with its Gateway as 172.12.xx.1

It also seemed as if things were not quite right when I was doing
some testing with a client machine using the Private IP pool, so
it would get an IP of 192.168.1.64.

I was able to connect to the server via external address, but
the login to the FTP server was unusually slow, and would
tend to crash on the LIST command after login if there was
a large number of files in the host directory.

Moved that client behind a Linksys router, and that problem
vanished. (I am sure there is nothing amiss with the server.)

The NVG510 doesn't seem to deal with DHCP very well.
I have that turned off on both the NVG510 and the Linksys.

Looking at the description of the options for that IP Passthrough
feature, I can see where it would be a good way for somebody
with a 1 IP package to make their PC visible, but it doesn't
seem to make sense if you are using the 5 public IP's.

At the moment I have a Linksys router configured with one
of the Public IP's, and a test linux server, which I have
only running FTP and a UnrealTournament server.

Currently still trying to get my production server working
from behind the Linksys.

For the test server I just configured the local LAN adapter
with one of the public IP's, but doing that for my
production server, is something I would really like to avoid
for a number of reasons. (Dozens of java beans compiled
with local IP hardcoded in them for one....)

I miss my Cayman.........

**Edit

Got the Linksys configured so my production server is working
fine behind it, with its old internal 198.168.1.xxx IP.

Client PC on the Linksys hits either FTP server fine now.
HTTP & the antique UT99 servers are back up also.

I brought back a site I wrote long ago, and set it as the default
for numeric access at »99.67.106.156/

I think it is up and running, but I can't actually test it from outside
the lan, as the NVG510 treats any IP I use as local. I am 1 hop
from any device on my network now, regardless of IP used it seems.

The various bot & random traffic is trickling into the logs, so I am
pretty sure it is working, but I miss the ability to confirm by
testing the server via either WAN or LAN.

If I wanted to put my "test" server back into production with one
of the other Public IP's I was given, and use an internal IP for its
lan adapter, it seems I will have to get another gateway/router
device to do the NAT.

I can configure multiple clients behind this linksys, and make them
work in harmony with 1 server, but I think that is all it can do.

I really miss my old Cayman.....

The ip passthrough option provides a quick easy way to avoid nat when there is only one public ip address.

Can you post more details about this?
You should be able to have the nvg510 lan dhcp server allocate public and private ip's
Or have the nvg510 lan dhcp server allocate private ip's only and you can manually allocate the public ip's

Trying to access/test your public ip from behind your modem/router is not a good idea during the time of setup.
I would always use another internet connection to test with dial up, smart phone ect.......

What was the model number and software version of the cayman?

There was no specific problem or errors while using the client
with the Private IP assigned by the nvg510. It just seemed
to be responding a bit sluggishly.... Specifically when connecting
to the FTP servers.

Got no other internet connection or smart phone to test with here.

The Caymans were 3546-002 models. Don't recall the software
version that was on them offhand.
