Hi,

I found in lwip user"s guide that talks about TTL. https://www.nongnu.org/lwip/2_0_x/group__lwip__opts__ipv4.html#ga556b9b58fd02c0fdd126791baef77411

First check the lwipopts.h file to see if you can customize lwip per your application requirements. Please also consult with lwIP forum for questions regarding the various flags you want to customize.
