Rewrite formdata or change inlinecode

[JJoe]

So your router's configuration page has an address like https://172.16.0.1/ ?
The code from that address contains the value that you want to change?

A Proxomitron filter may modify the value. However, if the code to be modified is encrypted (https), you will need to enable SSL filtering, http://www.proxomitron.info/45/help/CfgT5.html . DLLs at http://www.proxomitron.info/files/index.html .

Code:

[Patterns]
Name = "Sample"
Active = TRUE
URL = "172.16.0.1/"
Limit = 16
Match = "mtu.value<1440"
Replace = "mtu.value<yournumberhere"

Have you used the Proxomitron before?
Do you need to patch your Proxomitron's exe to allow RWIN greater than 32768?
