I succesfully set u a PPTP connection from one machine to a machine in China. I am now doing the same thing from another machine (different public IP) however I get the following on the server side: pptpd[9943]: CTRL: Client #.#.#.# control connection finished pptpd[10056]: CTRL: Client #.#.#.# control connection started pptpd[10056]: CTRL: Starting call (launching pppd, opening GRE) pppd[10068]: Plugin /usr/lib/pptpd/pptpd-logwtmp.so loaded. pppd[10068]: pppd 2.4.3 started by root, uid 0 pppd[10068]: Using interface ppp1 pppd[10068]: Connect: ppp1 <--> /dev/pts/3 pptpd[10056]: GRE: Bad checksum from pppd. for privacy I put #.#.#.# in place of the actual IP address just above in this message. I also get bad reads from GRE. This machine is also in China but different location. And it has a router IP address to come in which is different from its local IP address. I do allow 10 IP addresses in the ppptpd config or whatever. I get that error about 100 reduced to 10 for not enough IP addresses but I am guessing that is OK and it would allow 100 conenctions if you gave enough IP addresses. Anyway any idea why I get the above errors? My guess is it goes through more routers and maybe some routers are squelching or changing or inhibiting this GRE traffic? Make sense?
