In host2 I added default route for dev ppp0 using gw 10.100.0.2, which is that ip of host1. Any suggestion? I am really not used to networking techniques. I think the most important remarks are: host1 is the one that calls host2; on host1 I can do whathever I want, however host2 has a read-only file system, I can only add routes and change ...

pppd uses a default for "hisaddr" if it doesn't receive remote address info from the peer during IPCP. The address pppd uses is 0x0a404040 + unit where unit is the 0 in ppp0. That typically appears as 10.64.64.64. (The other default address you may see is 0xa707070 + unit = 10.112.112.112, used for dial-on-demand interfaces).

Eddy, thanks for the help to this point! tcpdump -n ip host 208.85.40.20 -i eth0 captures ping request/replys before touching the route table. Then after doing "route add 208.85.40.20 dev ppp0" and running tcpdump again with "tcpdump -n ip host 208.85.40.20 -i ppp0" it captures ping requests, but no reply back.

2020年7月25日 · The problem is when the main server switches off for any reason and disconnects from the both connections at a same time and re-establishes the connections, as ppp0 and ppp1 will be set by the main server itself, it is possible that it sets ppp0 and ppp1 shifted and certainly there will be big problems on that situation and we have to set the ...

I am doing this because I wanted to setup a VPN server and access that VPN using my cellphone. (My laptop and my cellphone share the same wifi). Initially, when I followed the instructions @ the Ubuntu's guide and I did a ifconfig, I got an interface called ppp0 and my cellphone was able to connect to the VPN. I then suspended my laptop for ...

2020年11月25日 · First you have to ensure, that the PI is using the 3g ppp0 connection for outgoing packets. ip route Should output something like: default via XXXXXX dev ppp0 Also, doing that curl you mentioned (with the proxy ip set to localhost) on the pi should give you the 3g address. 2. Check if local proxying works. After this: Try if local proxying works.
