One ISP and computer, two IP's in same subnet with DHCP

EgidijusL · 09-19-2017, 03:08 PM

IPTV project. The 1Gbs upload speed is not enough, it needs one additional addition.
I use the route, but it does not help much. Your link is linked to the balance, but I do not need it.
dhcpdump shows:
* IP: 0.0.0.0 (0:13:3b:f:48:e1)> 255.255.255.255 (ff:ff:ff:ff:ff:ff)

It is the same as applying to the required MAC address. (eth0 is 0:13:3b:f:48:e2)
Due to 255.255.255.255 I guess this is due to 169.254.0.0

The failover/load balance idea may be of some use here.

Guess wireshark might be used to see the dhcp handshake issue.

The 169 could be a problem as it may be defaulting before it can get new ip address.

Every once in a while a static arp entry can help if you are sending these to two modems. Kind a a bother if you forget it's there.

no, ZTE ZXHN F601 is an optical network terminal. It does not work as a modem.

I would look into treating each line as if that came from two different ISP's (even tho they are on the same subnet).
If it were me I would use WAN port 1 (from first ZTE ZXHN F601) and WAN port 2 (from second ZTE ZXHN F601) on this device https://www.cisco.com/c/en/us/produc...ter/index.html

The two options I needed in the past were:

PHP Code:



Smart Link Backup 
—Ensures continuous connectivity. If the primary WAN  
connection is unavailable, the backup WAN connection is used. Choose the  
primary WAN interface from the drop-down menu. 
 
Load Balance 
—Use both WAN connections simultaneously to increase the  
available bandwidth. The router balances the traffic between the two  
interfaces in a weighted round-robin method

You have to see what the max bandwidth the Cisco or any other unit can handle in load balance mode.

Would this be of any help to you: Net-ISP-Balance

Hello
I solved the old problem by setting up Mikrotik for one line (eth1).
Now I notice that when you open a nginx session on the computer via the external eth1 IP, there is no response.

Everything on a local computer (on a server). everything is fine with other remote networks:

I missed something?
