Which I thought was odd because of how natd + ppp -alias shares the same code. Its a p90 and only aliases about 5-6 hosts at most. I have thought of two ideas, my current mtu/mru is 296/296 I might try raising that to see if that has any effect. And I also was told to try disabling tcp_extensions in sysconfig.
