The question I have is fairly straight-forward, but the answer may not be. If I place a layer 3 device on Gn between an SGSN and a GGSN, is it possible to adjust MSS in TCP SYN packets? The packets are encapsulated by GTP so it will need to l ook down to the TCP header below the GTP header. If it is, what devices can perform this operation?
I have this problem too.
