Accessing Motorola config from networked PCs

Posts: 183

I have my Motorola VT1005V TA behind the WRT54G router, and it gets its IP address from the 54G. Everything works perfectly.

So why mess with it? Because it is there!

I know I can plug a pc's net cable into the lan port on the VT1005V and configure it via 192.168.102.1. I would like to be able to access it from the subnet of the PCs with ip addresses 192.168.1.{100-110}. The MTA gets ip address is 192.168.1.108, but I cannot access it on port 80 or 8080. Is there a known method to get into it? I didn't see a remote management option on the MTA.

I've already tried to put the entire network in the 192.168.102.* address space, but when I do that the MTA cannot get an IP address from the DHCP server on the 54G. Every other TCP/IP device (PCs, Tivos,etc) can. I have set all of the ip addresses and mac ids on the 54G admin page with non-expiring address leases so I can always find my resources where I expect them without having to worry about any other potentially variable items from the ISP (DNS,etc). When I set the IP addresses in the 192.168.1.* address space all of the DHCP works fine, but when I use the 192.168.102.* address space the VT1005V fails, as if its wan IP address and LAN IP address cannot be in the same subnet.

Any suggestions?

almahix,

My suspicion is that also the DHCP table from the 54G is assigning your MTA the ip address you mentioned in your post, your MTA also has a hard coded ip address in the config page. You need to change the hard coded ip address directly in your MTA.

The reason why you can't access the MTA is because the rest of the system is on a different subnet (i.e. the MTA is on 192.168.102 subnet while the 54G is giving everyone else an IP address with 192.168.1 subnet.

I have the same problem accessing my wireless AP because it is on a different subnet.

You can either change the hard coded ip address on your MTA by first connecting directly to it and change it to 192.168.1.120 or something that is outside your DHCP table then you should be able to access it that way.

Another option is the use the MTA behind the 54G and use the MTA as your DHCP table etc if it has that capability. Then you would need to disable the NAT and DHCP capabilities on the 54G.

I hope this helps. Mundy5
