I found this in your log:

Subnet mask does not match with subnet mask of master gateway.

... and..

Subnetmask of ECU(HU_NBT2, 0x63) is 255.255.0.0 [ParallelTask-3]

Subnet Mask of Master-Gateway (read from ECU)= 255.255.255.0 [ParallelTask-3]

Subnet masks of FEM-GW and NBT EVO do not match.

I use icom w router and use latest istap off line does not need wan connection but does not hurt if it does and loader 6.3 BB has fix for crash so use don't end up reinstalling istap

Thanks for the tip of using a router instead of a direct connection. I was able to program NBT and KOMBI successfully using ISTA and an ICOM NEXT.

FWIW, I didn’t have to do any of the config steps mentioned in this thread on my laptop, router, or ICOM. By default, my ICOM is configured using a static IP address (169.254.11.92), and it wasn’t assigned one by the router’s DHCP server. And my laptop is configured to use DHCP by default as well.

Thanks, It seems your router setup works perfectly. My problem was a loose wire

Do we still need DHCP server to program NBT and Kombi with Ista+ 4.3.14 when using ICOM A2?

Yes

Hi everyone,

I want to share my configuration that worked flawless:

First of all the ICOM should be configured this way:

ICOM Config

ConnectionMode = STATIC_IP
Ip = 192.168.68.85
Netmask = 255.255.255.0
Gateway = 192.168.68.99

Windows Ethernet config:

"Use the following IP Address"
IP 192.168.68.99
Subnet mask 255.255.255.0


Hope this help

I don't understand why you got ICOM with static IP 192.168.68.85 and with DHCP 192.168.68.1 IP? So ICOM with static IP or DHCP? Can't be both. The static IP will take presidence. Since the ICOM address is 192.168.68.85 why is the ROUTER_0=192.168.68.1 (that would be IP for ICOM from DHCP, but since the ICOM got static IP it won't use DHCP IP)?

Well I'm an IT tech, so those thing didn't look right to me. I assume we need the DHCP for control modules in the car not the laptop/ICOM itself. Laptop/ICOM won't be restarting during the update, so there is no need for them to get new IP's. Modules of the car will be restarting so I assume they need to get new IP's during update.

Would be nice to get a technical document that got some real information on what actually happens during update, so it would be easier to understand the best way to config system. I haven't tried that config, because I don't like to use something that doesn't seem right. I'm not trying to be a smart ass here, I just want to understand what is the best practice to avoid any issues with update.

Actually the gateway setting on ICOM is not required, as the traffic won't leave from the subnet.
All we need are, static IP on ICOM, static IP on computer, a hard or soft dhcpd in the subnet.
When the NBT boot up / restart, it will obtain IP for itself for communication; and the KOMBI with MOST fibre connection to NBT, will treat NBT as their gateway. So if NBT cannot get IP, KOMBI will be update fail too.
