It appears you are on Comtrash where everything is CoMtRaSHtIc.
Good for you. Dance a jig.
Stop beating the MTU horse to death and get busy finding out how to best
connect to the CPE devices.
Google that stuff.
First, when testing, disable (admin down) the internal network on the second
Also, check to see what specific nics you have an if any recent issues with
kernels and such and any updates.
Google that too.
Then Focus on the internet transit/transport infrastructure.
Find out best way to interface with the cable modem CPE infrastructure.
Meaning what speed and duplex.
Trial and error.
You will get there...
Some nics need to be played with and dealt with in terms of kernel and other
things like disable ipv6 in modprobe.conf and dhcp...
You might be better off having an intermediate device between you and the
cable modem if your nics don't wanna play nice with the cable modem.
Last but not least, you can always check stats and see if collisions and
errors on interfaces and more.
