Could it be that my strongswan does not handle my case well?
My case is such that:
a) my server runs a client to a "public" VPN of which end I
know almost nothing - this part works well.
b) my server is also the server for my own VPN clients - and
here is where I cannot access those roadwarriors (but they
can ping server's LAN)
Here is when a roadwarrior connects okey and server show
this for table 220:
10.3.9.1 dev ipsec0 table 220 proto static src 10.3.1.101 (a
client connected to my server, pool for clients is
10.3.9.0/24 while server's LAN is 10.3.1.0/24)
172.16.0.0/12 dev ipsec0 table 220 proto static src
172.16.32.73 (server is client to a public VPN)
If I'm not asking too much then I wonder - is it the
strongswan not doing something or doing something wrong but
can be helped somehow? (config/plugin/hooks etc.)
Or it's exclusively OS firewall/routing which needs fixing
outside and independently of strongswan? (but then it would
sort of defeat the purpose of strongswan in my opinion)
ps. If I give clients the pool of "dhcp" so roadwarriors
land on the same server's LAN then 'ping' to roadwarriors
works, but erratically.
many thanks, L
