Have a Hotspot with the wlan1 bridged with a EoIP tunnel. Tried multiple MTU settings on the EoIP tunnels. At 1458 MTU can get to regular websites etc. Anything larger don’t work. However, tried down to 900 MTU and we can’t get onto http://www.gmail.com etc. This redirects to a secure site.
Any thoughts?
do you have conntrack enabled each end of the eoip?
Yes, the answer to this is that you have to put change MSS rules in for your EoIP Tunnels.
I have a similiar setup / problem. I’ve bridged l2tp tunnels and set MRRU to 1500. The MRU of the profile is 1460. Traffic passes, but anything 1500 bytes does not. I have the PPP profile set to ‘change tcp mss’ but it’s not doing its job.
Shouldnt ‘change tcp mss’ insert some dynamic Mangle rules ? It’s not …
