[Amportal-users] NAT Problems** :( :L) Pulling My hair out

Well with the issues you are are having, I would just use iptables on the asterisk box, get it working right…the strange problems should be trouble shot with the least amount on gear as possible.

If you can not get it working using iptables on the box you have upstream issues…

get it working for 48 hours then start with one thing at a time until you kill it or you get it all back in one wad…

IAX just works I it is best route for testing…

Now I have to ask this as it can be the root of all your issues.

You do have a PUBLIC ip for your firewall right???

You are not connected to device from your ISP that gives out a PRIVATE ip right???

I only ask this because I have seen where some folks ASSUME the ip they have is PUBLIC as it isa the WAN side of a router / firewall…yet they failed to understand the ISP device was natting the connection (not in bridged mode)
DSL from bells are good at this…

Yes people send me 192.168.x.x IP’s ALL THE TIME to SSH into their boxes…

Bubba,

I have what I think is a public ip address. It was sold as a static ip. It is 72.0.72.x .

PBX working fine in LAN with multiple soft IAX phones.

PBX seems to work fine with “port switch” previously mentioned for remote extensions in home LAN.

I may be able to connect pbx to internet but have to figure out setup of lan and voip lan.

I will get back to you on this.

Thanks

Regards

Peter

No sir you assume wrong

IAX can have MANY MANY connection’s behind a natted device (i sit here with five iax extens on five different servers)

what causes many users issues is SPI (Stateful Packet Inspection)

SIP traffic is very busy… lots of traffic for nothing…so GOOD router will
Say Hey this traffic looks like a DDOS attack let me kill it…

so if you got a smart router dumb it down by killing SPI…
get it working then enable it back if you still have problems kill it…

NOW sip that is the problem child, and with sip you can have them on the same port SOMETIMES it is a router issue I think…

but IAX does need any changing…it just works…

Using Tomcat but need to do more? Need to support web services, security?

Bubba,

Thanks, sort of.

I have a Netgear FVS124G from their business line of wired vpn/routers. It even has dual WAN ports. So I suspect they think it is “smart”. From my point of view, it has been a pain! I think your right but I have yet to figure out how to this on this particular router.

I would gladly use my retail Netgear but it seems to lose connection from time to time and not reconnect all the time.

I have IPcop at home and would also gladly replace my router at the office with this IPcop as long as it would not cause me any troubles.

Can you offer any assistance with this router?

Do you do any consulting/custom development? As per a post in development forum, I need some help with a small project with my box. As in that post, I am happy if most if not all of the work done on my project can be plowed back into FreePbx.
