MTU for IPSec (Remote Access)

JeffCooper

Hi,

Is there a way to set the MTU for the IPSec Remote Access VPN on an XGS2300 v19? I'd like to se if tweaking it improves performance for my remote users.

Thanks,

Jeff

    Hello ,

    Thank you for reaching out to the community, you may find the example of the useful commands below:
    iptables -t mangle -I POSTROUTING -s X.X.X.X/X -d Y.Y.Y.Y/Y -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --set-mss 1300;
    iptables -t mangle -I POSTROUTING -s Y.Y.Y.Y/Y -d X.X.X.X/X -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --set-mss 1300;

    OR You can change the WAN interface MSS Values !! 

    Thanks & Regards,
