Příloha:
Zdravím, nevedel by mi niekto pomôcť s návrhom VPN? Problém je ten, že nedokážem vytvoriť spojenie, ktoré by umožňovalo vzájomnú komunikáciu medzi klientmi. Skúšal som TAP a TUN, ale bez úspechov. Ak by bol niekto ochotný a vysvetlil by mi problematiku tohto riešenia pretože sa s tým už trápim skoro dva týždne a bez výsledkov... Požiadavka je, aby prideľovanie IP adries prebehne pomocou certifikátov / CCD. Budem veľmi vďačný za pomoc.

Jako problem bych videl identicke LAN za kazdym VPN klientem. Pokud takova zarizeni maji komunikovat mezi sebou a nemuzes konfigurovat rozdilne site, budes je muset zamaskovat.

Jak vypada tva aktualni konfigurace klient/server?

Ahoj, tak nakoniec sa mi to podarilo rozbehnúť, ale problém mám sem tam s clientom pod windowsom. Musím vypnúť firewall (snažil som sa manuálne pridať do esetu novú bezpečnú zónu, ale nefunguje to) a tak sa pripájať. A aj to nie vždy sa podarí. Niekedy je pripojenie s chybami a vôbec nepracuje. Musím vypnúť OpenVPN a zastaviť a znova spustiť sieťový adaptér "TAP-Windows Adapter V9". Na druhý alebo tretí pokus sa to podarí.Linuxový klienti sú bez akýchkoľvek komplikácii
