wanted to link two offices over their dial‑up modems (RAS vs VPN). As noted, the exact procedure depends on the operating system; pointed to VPN resources and suggested searching, so the short, practical summary below distills the common, still‑relevant options.

A direct dial‑up (PPP) RAS link

  • One PC must act as the answerer (auto‑answer modem) and accept incoming PPP calls. On Windows desktop OSes use the Incoming Connections feature (server OS uses RRAS); on Unix/Linux use an answering daemon with pppd. Configure a dial‑in user, enable "allow callers to access my network", and either assign static IPs or let PPP hand out fixed addresses (see the pppd manual for options).
  • Common problems to check: modem handshake (AT commands), disable PSTN call‑waiting, correct COM/USB modem driver, matching authentication settings (PAP/CHAP/MS‑CHAPv2), and firewall rules allowing routed traffic.

Security and alternatives

  • Dial‑up is slow (single low‑speed link) and limited in security. Where possible, prefer a site‑to‑site VPN over an always‑on internet link or use router‑to‑router VPNs (OpenVPN, WireGuard) for better performance and modern cryptography.
  • Microsoft RRAS documentation explains Windows server dial‑in and routing; the pppd manual documents Unix/Linux setup. For modern VPN choices see OpenVPN or WireGuard.

References: Microsoft RRAS documentation (Routing and Remote Access) (), pppd manual (https://man7.org/linux/man-pages/man8/pppd.8.html), OpenVPN (https://openvpn.net/), WireGuard (https://www.wireguard.com/).
